Document Type and Number:
Japanese Patent JP7017030
Kind Code:
B2
Abstract:
This invention provides a solution for a silicone hydrogel contact lens, which may improve the surface hydrophilicity and surface lubricity of a silicone hydrogel contact lens. The solution for the silicone hydrogel contact lens contains a copolymer (P) having structural units represented by the following formulas (1a) to (1c) and a water-soluble polymer (Q), wherein the ratio na:nb:nc of the structural units in the copolymer (P) is 100:10-400:2-50. In the formulas (1a) to (1c) of [Chemical Formula 1] [Chemical Formula 2] [Chemical Formula 3], R1, R2 and R5 are each independently hydrogen atom or a methyl group; R3 and R4 are each independently a hydrogen atom, a methyl group or an ethyl group, or bonded to each other to form a morpholinyl group; and R6 is a hydrocarbyl group having 12 to 24 carbon atoms.
