Abstract
A process for producing decorative sheets having an embossed pattern corresponding to a printed pattern layer, the process including the steps of: (a) forming a printed pattern layer on a base paper of the decorative sheet by use of a printing ink containing (i) a curing agent or a polymerization catalyst and (ii) a curable rein, the curing or catalytic action of the curing agent and polymerization catalyst being blocked and thereby inactivated, the printing ink being liquid repellant; (b) releasing the blocked state of the curing agent or polymerization catalyst thereby curing the curable resin in the printed pattern layer; (c) coating the whole surface of the printed pattern layer with a coating agent for formation of a top coating layer; and (d) solidifying the coating agent thereby forming the top coating layer of which the portions corresponding to the liquid repellant printed pattern layer are concaved.
