摘要： A water-absorptive contact lens made of a copolymer comprising units of an ester of acrylic or methacrylic acid and at least one saccharide selected from D-galactose, D-glucose and D-mannose and units of at least one member selected from a hydrophilic monomer and a hydrophobic monomer, which has excellent oxygen permeability and affinity for the eye and can be worn continuously for a long period of time. The contact lens is prepared by polymerizing a monomer mixture containing an ester of acrylic or methacrylic acid with a ketalized saccharide and a hydrophilic monomer and/or a hydrophobic monomer, and after forming the resulting copolymer into a contact lens, if necessary, treating the copolymer having a shape of contact lens with an acid to convert the ketal groups into hydroxyl groups.

摘要： A method of coloring a water-absorbable plastic partially or totally in a single color or multiple colors in such a manner that no migration or separation of the coloring agents used can take place. A copolymer of a coupler monomer and a water-absorbable plastic monomer, a polymer of a coupler polymer and a water-absorbable plastic monomer or a polymer of a coupler monomer and a water-absorbable plastic polymer is formed into an intermediate product shaped in the form of any desired final product. The intermediate product is immersed in an aqueous solution of a developer consisting of a diazonium double salt and allowed to swell, whereby the diazo-component of the developer penetrates into the plastic. The swollen product is then immersed in an aqueous acid or alkaline solution having an optimum pH value for coupling reaction to allow formation of an azoic dye on the plastic as a result of the coupling reaction. A partially colored plastic is produced by application of ultraviolet rays to a portion or portions of the plastic on which no coloring is required, whereby the diazo-component on those portions is decomposed to leave those portions uncolored. Multiple coloring is effected by repeating the partial coloring process by changing diazonium double salts.
