Abstract: A contact lens and a manufacturing method thereof are provided. The contact lens includes a lens and a hydrophilic polymer layer. The hydrophilic polymer layer and the lens are entangled with each other. The hydrophilic polymer layer and the lens form an interpenetrating polymer network or a semi-interpenetrating polymer network. The hydrophilic polymer layer is formed by polymerizing an initiator adsorbed on the lens with at least one hydrophilic vinyl monomer. The contact lens has excellent hydrophilicity. Since the manufacturing process of the contact lens is simple, the manufacturing efficiency can be improved, and the manufacturing cost can be reduced. Moreover, the manufacturing method can be applied to lenses made of various materials and used for their surface modification, so it is widely applicable.

Abstract: Provided are a biodegradable resin aqueous dispersion from which a transparent film with an excellent biodegradability can be obtained without impairing the properties inherent to resins, and without performing a special heating treatment; a film forming agent using such dispersion; and a method for forming a film. The biodegradable resin aqueous dispersion of the present invention is an aqueous dispersion with a biodegradable resin being dispersed in an aqueous solvent under the presence of a non-ionic dispersant, comprising, as the biodegradable resin, a polycaprolactone having a weight-average molecular weight of 20,000 to 90,000, wherein a mass ratio of the non-ionic dispersant to the biodegradable resin is 0.03 to 0.23.
