【表】DETAILED DESCRIPTION OF THE INVENTION This invention involves applying a pattern to a sheet-like water-soluble support with a printing ink or paint capable of forming a coating film with a water contact angle of 50 to 80°, and then applying a pattern to the water-soluble support. The present invention relates to a method of printing by transferring a synthetic resin article floating on the water surface by pressing it against a water-soluble support, allowing all or part of the article to settle, and then transferring and printing using hydraulic pressure. The above-mentioned hydraulic transfer printing method has been proposed in Japanese Patent Publication No. 41682/1982 as a printing method for three-dimensional surfaces (uneven surfaces) of synthetic resin molded products and the like. However, in the case of this method, the adhesion (adhesion) of the printing ink etc. to the transferred surface is insufficient, and the resulting transfer printed surface often cannot withstand the taping test (so-called goblin test). It has been difficult to apply it as it is to articles that require a high degree of weather resistance, abrasion resistance, etc., such as interior and exterior parts of automobiles. In view of the above, the present invention provides a hydraulic transfer printing method that has good adhesion on the transfer printing surface and can also be applied to articles that require high weather resistance and abrasion resistance. The purpose is to The hydraulic transfer printing method of this invention has a water contact angle of 50~
When a water-soluble support patterned with a printing ink or paint capable of forming an 80° coating film is floated on the water surface and transferred to a synthetic resin transfer object using hydraulic pressure, the water-soluble support is patterned immediately before transfer. Spray thinner with an SP value of 7 to 11 cal1/2 cm -3/2 on the pattern-attached surface or transfer surface of the support, and after transfer, apply a water contact angle of 50 to 80, which has excellent weather resistance and abrasion resistance. The above object is achieved by forming a transparent coating film of .degree. on the transfer printing surface. Hereinafter, the method of the present invention will be explained based on illustrated examples. (1) Water contact angle (hereinafter simply referred to as "contact angle")50
A pattern is applied onto a sheet-shaped water-soluble support 2 using a printing ink or coating material 1 capable of forming a coating film of up to 80°. In the above, the printing ink or paint (hereinafter abbreviated as "printing ink, etc.") that can form a coating film with a contact angle of 50 to 80 degrees is used because:
This is to improve the adhesion of printing ink, etc. to the transfer object made of synthetic resin (the contact angle of most synthetic resin molded objects is 50 to 80 degrees). The film-forming element for these printing inks and the like is preferably a urethane-based material having excellent physical properties and stretchability, but it may also be an acrylic-based material, a polyester-based material, an epoxy-based material, or a mixture thereof. Materials for the water-soluble support include polyvinyl alcohol (PVAL),
There are no particular limitations on synthetic or natural materials as long as they dissolve quickly in water, such as glue, starch, cellulose, agar, etc. How to apply the pattern on the water-soluble support
It is not limited to ordinary convex or concave printing, but may also be painted using a masking method or the like. Any form of pattern can be applied, such as wood grain, floral patterns, marble, animals, cartoon characters, geometric patterns, etc. (2) With the water-soluble support 2 obtained in (1) above floating on the water surface W as shown in FIG. Alternatively, a portion may be settled and transferred using hydraulic pressure. At this time, immediately before transfer, the pattern of the water-soluble support 2 is applied to the adhering surface or the transfer surface of the transfer object 3.
Spray thinner with an SP value (dissolution parameter) of 7 to 11 cal 1/2 cm -3/2 to soften the printing ink, etc. 1. It is presumed that this softening effect improves the adhesion of printing ink and the like to the transfer surface. The SP value of the thinner is 7 to 11cal1/2·cm-3/2, which is within the range of compatibility with printing ink, etc. Specifically, aromatics include toluene, xylene, etc., esters include methyl acetate, ethyl acetate,
MEK as a ketone, such as isobutyl acetate,
MIBK, etc., cellosolve (product name: manufactured by UCC)
Examples include cellosolve acetate and cellosolve butyl, but usually a mixture of these is used. The synthetic resin material of the transferred article has a contact angle of 50 to 80°.
Thermoplastic resins such as ABS, PC, PMMA, AS, PS, polyphenylene oxide, PF, UP,
Thermosetting resins such as EP are preferred, but PE, PP
Even resins with low surface activity can be applied by primer treatment or surface activation treatment using plasma or the like. (3) After the transfer in (2) above, the water-soluble support remaining on the transferred article 3 is washed off and dried to form a transparent coating film 5 with a contact angle of 50 to 80° with excellent weather resistance and abrasion resistance. is formed on the transfer printing surface 1 (see FIG. 2). The reason why the contact angle of the transparent coating film 5 is 50 to 80° is to approximate the contact angle of a coating film formed with printing ink or the like, thereby improving adhesion to the transfer printing surface. Further, as the material for forming the transparent coating film 5, polyurethane is most desirable in terms of physical properties, but acrylic resin, polyester resin, etc. may also be used. Further, the coating film thickness is 5 to 40μ. The transfer printing surface applied to the synthetic resin transfer object in this way has good adhesion to the transfer surface, as is clear from the examples below, and
Since it is protected by a transparent coating with excellent weather resistance and abrasion resistance, it can also be applied to interior and exterior parts of automobiles used under harsh conditions. Next, Examples will be shown, and the transferred articles and test items are as follows. <Articles to be transferred> First example... ABS resin automobile meter panel (width 400 x length 250 x depth 100 x plate thickness 3 mm) Second example... ABS resin automobile meter panel (width 300 x length 200 x depth 50 x plate thickness 3 mm) 3rd example: ABS resin automobile meter panel (shape is the same as the 2nd example) <Test method> (a) Abrasion resistance: Taper abrasion tester CS-10 (Taper Co., Ltd.) The degree of wear was checked by rotating the test piece at a speed of 100 rpm while applying a load of 500 g. (b) Moisture resistance: After leaving the test piece in an atmosphere of 40°C x 95% RH for 400 hours, a taping peel test was conducted to check for peeling. (c) Light resistance: After irradiating the test piece with ultraviolet rays for 800 hours using a fade meter (manufactured by Suga Test Instruments Co., Ltd.), a taping peel test was conducted to check for peeling. (d) Acid resistance…Place the test piece in 0.1NH 2 SO 4 aq (room temperature).
After 24 hours of immersion, the samples were visually checked for appearance abnormalities (blisters, whitening, etc.). (e) Alkali resistance...Abnormal appearance (blister, whitening, etc.) after immersing the test piece in 0.1N NaOHaq (room temperature) for 24 hours.
A visual check was made to see if there was any. <First example> Two-component acrylic urethane ink (coating film contact angle
A water-soluble support (PVAL with M W 800, thickness 10 μm) with a wood grain pattern printed at an angle of 66°) was floated on the water surface.
Mix thinner (toluene, MEK,
MIBK, cellosolve acetate, and ethyl acetate (consisting of equivalent weight ratios) are sprayed onto the printing surface, and the transferred article is slowly allowed to settle while being pressed against a water-soluble support (sedimentation speed: 100 cm/min). After the transfer, the residue of the water-soluble support on the transferred article is washed off with water and dried at 70°C for 60 minutes, and then a two-component acrylic urethane paint (film contact angle 65°) is applied to the transfer printing surface with a thickness of 20 μm. A transparent coating film was formed by coating the film to a thickness of 100°C and curing it at 70°C for 60 minutes. The resulting transfer printed surface showed a beautiful grain pattern and exhibited excellent physical properties as shown in Table 1. <Second Example> One-component acrylic urethane ink (contact angle coating film)
A water-soluble support (PVAL of M W 2000, thickness 3 μm) with a floral pattern printed at an angle of 64°) was floated on the water surface.
Immediately before transfer, mixed thinner (same as in the first example) was sprayed onto the printing surface, and the transferred article was slowly allowed to settle while being pressed against a water-soluble support (sedimentation speed: 150 cm/min). After sufficient transfer,
The residue of the water-soluble support on the transferred article was washed off with water and dried at 70°C for 30 minutes, and then a two-component polyester urethane paint (film contact angle 61°) was applied to a thickness of 15 μm on the transfer printing surface. A transparent coating film was formed by applying the coating to a substrate and curing it at 70°C for 60 minutes. The obtained transfer printing surface showed a beautiful floral pattern, and the test results were the same as in the first example (Table 1), especially in terms of abrasion resistance.
There were no abnormalities even after 700 cycles. <Third Example> A water-soluble support (cellulose of M W 2000, thickness 5 μm) on which a marble pattern was printed with epoxy ink (contact angle of coating film 68°) was floated on the water surface and mixed with thinner immediately before transfer. (composed of toluene, MEK, and ethyl acetate in the same weight ratio) was sprayed onto the printing surface, and the transferred article was slowly allowed to settle while being pressed against a water-soluble support (sedimentation rate: 100%).
cm/min) After sufficient transfer, the residue of the water-soluble support on the transferred article is washed off with water and dried at 70°C for 45 minutes, and then a two-component acrylic urethane paint (film contact angle 63°) is applied. It was applied to a thickness of 20 μm on the transfer printing surface and cured at 70° C. x 60 mm to form a transparent coating film. The resulting transfer printing surface shows a beautiful marble pattern,
The test results are the same as in the first example (Table 1),
In particular, the wear resistance remained unchanged even after 800 cycles. In addition, in any of the examples, when the transfer was performed without spraying thinner, the adhesion of the transfer printing surface to the transferred surface was not good, and even if it was protected with a transparent coating, it could withstand each physical property test from the beginning. It wasn't. 【table】
