Abstract
Description
The present invention relates to a composition for printing a color hard contact lens, and more particularly, to a composition for printing a color hard contact lens that prints irises of various colors and patterns around the front outer periphery of a hard contact lens.
In general, people with poor visual acuity or astigmatism use glasses or contact lenses, and contact lenses are often used because they are uncomfortable to wear but are not exposed.
Contact lenses are classified into soft contact lenses of disposable or regular replacement type which are made of soft materials according to the material of the lens and can be used for a short time or short time, hard contact lenses which are made of hard materials and can be used for a long time or for a long time. do.
In addition to the unique task of contact lenses, called contact correction, contact lenses are developed in various colors to achieve a cosmetic effect. Color contact lenses are another product because of the aesthetic desire of women and product development performance .
That is to say, people with good eyesight can also improve appearance, that is, a color contact lens in which irises of various colors and patterns are formed on the outer portion of the contact lens so as to change the color of the pupil to another color such as blue, .
In particular, as the world becomes global, the exchange between different races and cultures increases, and the demand for color contact lenses, which can change the color of the pupils, is further increased.
There are two main types of contact lenses: transparent contact lenses. Transparent contact lenses have been developed to emphasize transparency rather than to change the original iris color, or to block rays of light. Therefore, the transparent colored contact lens has a limitation in changing the pupil to a desired color, and thus it is used for identification purpose or ultraviolet ray shielding rather than beauty use.
The second is an opaque colored contact lens that can change the original iris color to another color. However, since the size of the opaque pigment used in this lens is generally larger than the pore size of the soft contact lens, there is a problem that it is difficult to color the pigment directly on the lens.
Such a conventional color contact lens has a structure in which a pupil portion of a pupil is made transparent in the eye and a predetermined color or shape is put in a portion having a larger size so that the size of the pupil is larger when people see it, As shown in Fig.
That is, the contact lens is composed of a lens portion formed in a transparent portion of the contact lens so as not to block the pupil, and an extension portion formed on an outer portion of the lens portion and formed so that the pupils are partially overlapped with each other, .
Such an extension part deposits a pigment such as a predetermined shape and a black color so that the pupil looks bigger when worn on the eyes or the color of the pupil is changed by other colors or the like.
That is, such a color contact lens is used for eye cosmetic use rather than for visual correction, so that the size of the pupil is made large and the color is colored so that the eye looks more beautiful.
In such a conventional color contact lens, an iris pattern can be formed only on the contact lens, and it is difficult to form the contact lens, and a color soft contact lens is mainly used.
In addition, such a color soft contact lens is complicated in the printing of the iris pattern, and in particular, the iris pattern is not secured with the hard contact lens, so that the durability of the hard contact lens is deteriorated.

The composition for printing a color hard contact lens of the present embodiment comprises a resin material, a binder, a solvent, a binder, and a polymerization inhibitor. The color hard material is mixed with a pigment to print an iris pattern on the front surface of the hard contact lens. Is a composition for printing contact lenses.
Resin is a raw material for a synthetic resin which forms a synthetic resin by polymerization, and is made of methyl methacrylate and forms a methacrylate resin by polymerization.
Methyl methacrylate is a colorless transparent liquid organic compound that produces polymerization well. It is produced by reacting acetone with hydrogen cyanide to form acetone cyanidehydrin, dehydrating it with concentrated sulfuric acid, and treating it with methanol.
Such methyl methacrylate is a colorless and transparent liquid having an ester odor. It is slightly soluble in water but is easily dissolved in most organic solvents and easily polymerized by light, heat, radiation, peroxide, etc., Glass and the like, and is used as a raw material for a methacrylic resin or an unsaturated polyester resin.
A methacrylate resin is a thermoplastic resin produced by polymerization of acetone with methylene methacrylate derived from isobutylene and methanol, and has a specific gravity of 1.17 and a softening point of 80 to 100 ° C.
The methacrylic resin is a plastic with the highest transparency and has an ultraviolet transmittance of about 92%, which is higher than that of ordinary glass, has almost no absorption of visible light over the entire wavelength, has transparency and outstanding weatherability, Strength, and the like, and is used in a wide range of applications.
In particular, methacrylic resins are widely used for illumination related applications such as automobile tail lamp covers, lighting apparatuses, advertisement display panels, fluorescent lamp covers, and the like.
The methacrylic resin is a kind of thermoplastic resin and is lightweight, strong, colorless and transparent. It is widely used for windproof glass of an aircraft and an automobile, an electric lighting fixture, a signboard with an electric lamp inside, a greenhouse, an electric fan blade, a building material, a contact lens and the like because it can freely color and is excellent in weather resistance and light fastness.
It is preferable that such a resin agent is composed of 3 to 5% by weight of a resin based on 100% by weight of the total composition for printing of a color hard contact lens.
