Abstract
PURPOSE: To obtain a highly accurate mold for forming plastic sheets and the like made of a very hard, resistant, light sensitive, synthetic resin on which fine pattern with concave and convex parts is scribed by optochemical means.
CONSTITUTION: The very hard, heat resistant, light sensitive, synthetic resin is characterized by the heat resistance against 100°C or more, and the hardness of 60° or more which is measured by Shore D type hardness tester. Radical polimerization is caused by the light having the wavelength of about 250W450nm in said resin, and the resin become insoluble. The concave and convex pattern is made by an optochemical means, and the mold of the plastic sheets and the like is manufactured. Said light sensitive resin is composed of; (A), bonding agent such as saturated polyester, polyamide, polyurethane, polyacrylacrylic ester; (B), vinyl series monomer such as acrylamide; (C), polymerization initiator such as benzoin; and (D), thermal polymerization inhibitor such as methyl hydroquinone.
