【Example】

Example I A transparent base paper sheet was prepared as follows. A mixture of 70% by weight of hydroxypropylmethylcellulose (K35LV, obtained from Dow Chemical Co.) and 30% by weight of various additive components respectively obtained from Aldrich Chemical Co.,
56 g of hydroxypropylmethyl cellulose and 24 g of the additive component were mixed with 1,000 milliliters of water in a 2-liter wide-mouth bottle, and the contents were prepared by stirring with an omni homogenizer for 2 hours. The solution was then left overnight to remove air bubbles. Next, a 100-micron-thick cut sheet-like (8.5 × 11 inch) Mylar base sheet was prepared, and the prepared mixture was applied by a dip coating method (double-side application in one operation). 25 °
After air-drying at C for 3 hours and then at 100 ° C. for 10 minutes in an oven, the difference in weight before and after coating was examined. As a result, 1 g of each dried coating sheet was coated on each side of the substrate with a thickness of 10 μm. (Total coating weight of 2 g on the two-sided transparent base paper). For comparison, transparent base paper sheets were also prepared in which the coating consisted of 100% by weight of hydroxypropylmethylcellulose and contained no additive components.

The prepared transparent base paper sheet was loaded into a Hewlett Packard 500-C color ink jet printer containing the inks of the following components: Cyan: 20% by weight ethylene glycol, 2.5% by weight benzyl alcohol, 1.9% by weight. Ammonium chloride, 0.1 wt% Dow Chemical 150, Dowicil 150 fungicide from Midland, MI, 0.05 wt% Polyethylene oxide (molecular weight 18,500) from Union Carbide, 30 wt% from ICI Projet Cyan 1 dye, 45.45 wt% water.

RN-3000) 36 wt% and various additive components 10 wt% each obtained from Aldrich Chemical Co.
g, poly (ethylene oxide) 28.8 g, and additive component 8 g were mixed with 1,000 ml of water in a 2-liter wide-mouth bottle, and the contents were prepared by stirring for 2 hours with an omni homogenizer. The solution was then left overnight to remove air bubbles. Next, a 100-micron-thick cut sheet-like (8.5 × 11 inch) Mylar base sheet was prepared, and the prepared mixture was applied by a dip coating method (double-side application in one operation). After air-drying at 25 ° C for 3 hours and then drying in an oven at 100 ° C for 10 minutes, the difference in weight before and after coating was examined. 1 g of each of the dried coating sheets was 10 μm thick on each side of the substrate. It was coated (total coating weight of 2 g on two-sided transparent base paper). For comparison, the coating was 60% by weight hydroxypropylmethylcellulose and 40% poly (ethylene oxide).
A transparent base paper sheet consisting of wt% and containing no added components was also prepared.

The prepared transparent base paper sheet was loaded into a Hewlett Packard 500-C color ink jet printer containing the inks of the following components: Cyan: Same as Example I.

Magenta: Same as Example I.

Yellow: Same as Example I.

Image formation was carried out by printing cyan, magenta, yellow and black block patterns. The image formed was left to dry at 25 ° C.

[0059]

[Table 2] As shown in the results, the drying time of the transparent base paper containing the additives was generally faster than that of the transparent base paper containing no additives. Furthermore, the optical densities of the images on the transparent base paper with the additives were in all cases acceptable.

Example III A transparent base paper sheet was prepared as follows. A mixture of 90% by weight of hydroxypropylmethylcellulose (K35LV, obtained from Dow Chemical Co.) and 10% by weight of various additive components respectively obtained from Aldrich Chemical Co.,
72 g of hydroxypropylmethyl cellulose and 8 g of the additive component were mixed with 1,000 milliliters of water in a 2-liter wide-mouth bottle, and the contents were prepared by stirring for 2 hours with an omni homogenizer. The solution was then left overnight to remove air bubbles. Next, a 100-micron-thick cut sheet-like (8.5 × 11 inch) Mylar base sheet was prepared, and the prepared mixture was applied by a dip coating method (double-side application in one operation). 25 ° C
It was air-dried for 3 hours, then dried in an oven at 100 ° C. for 10 minutes, and the weight difference before and after coating was examined. As a result, 1 g of each of the dried coating sheets was coated on each side of the substrate with a thickness of 10 μm. (2 g total coating weight for two-sided transparent base paper). For comparison, a transparent base paper sheet was also prepared in which the coating consisted of 100% by weight of hydroxypropylmethylcellulose and contained no added components.

The prepared transparent base paper sheet was loaded into a Hewlett Packard 500-C color ink jet printer containing the inks of the following components: Cyan: Same as Example I.

Magenta: same as in Example I.

Yellow: Same as Example I.

Images were formed by printing block patterns of cyan, magenta, yellow and black. The image formed was left to dry at 25 ° C. The black image was "process black" (ie, formed by superimposing the cyan, magenta and yellow images). The drying time and optical density of the generated image are shown in Table 3 below.

[Table 3] As shown in the results, the drying time of the transparent base paper containing the additives was generally faster than that of the transparent base paper containing no additives. Further, the optical density of the image on the transparent base paper containing the additive was within the allowable range, and in some cases, it was improved as compared with the transparent base paper containing no additive.

Example IV A sheet of recording paper was prepared as follows. Each coating composition containing various additive components obtained from Aldrich Chemical Co. was added with 50 g of each additive in water in a beaker.
It was prepared by dissolving in 00 milliliter and stirring at 25 ° C for 1 hour. Next, a 100-micron-thick cut sheet-like (8.5 × 11 inch) paper base sheet was prepared, and the prepared additive solution was applied by the dip coating method (double-side application in one operation). 1 at 100 ° C
After air-drying for 0 minutes and examining the weight difference before and after coating, each sheet was found to have 500 mg (total coating weight of 1 g for a two-sided sheet) of additive component coated on each side in a thickness of 5 microns. It was For comparison, an uncoated paper sheet treated with a composition containing only water in the same formulation was also imaged.

The prepared paper sheet was loaded into a Hewlett Packard 500-C color ink jet printer containing the following ink components: Cyan: Same as Example I.

Magenta: same as in Example I.

Yellow: Same as Example I.

Imaging was done by 100 percent ink application. After printing the image, each of the paper sheets was accurately weighed with a precision balance at time zero and at certain time intervals thereafter. The difference in weight was recorded as a function of time, considering 100 minutes as the maximum time required for most of the volatile components of the ink to evaporate.
It was considered to be an ink component, such as water or glycol, that can evaporate when compared to components such as dyes, salts and / or other non-volatile components. If you know the weight of the deposited ink at zero time, you can calculate the amount of volatile components in the image). After 1000 minutes, the curl value of the paper sheet was measured. The values are listed in Tables 4 and 5 below. The black image was "process black" (ie, formed by superimposing the cyan, magenta and yellow images).
