专利汇可以提供Printing layer and production thereof专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a gravue printing layer enhanced in resistance to water, solvents and heat, by previously coating a printing surface with a water-insoluble resin varnish comprising a component which becomes water-insoluble by reacting with a base component of a gravue ink. CONSTITUTION:First, the printing surface of a printing paper or the like is coated with a water-insoluble resin varnish comprising (A) a component which becomes water-insoluble by reacting with a base component of a gravue ink, by gravue coating or roll coating. Next, desired patterns are printed on the coated layer of the varnish in a gravue ink comprising (B) a component capable of reacting with the component A as a base, followed by heating to 90-200 deg.C to bring the component A in the varnish and the component B in the gravue ink into reaction with each other, thereby obtaining the objective printing layer. The use of an acrylic resin modified with a melamine resin or the like as the component B in combination with methyl glucoside as the component A is preferably in view of heat resistance or the like.，下面是Printing layer and production thereof专利的具体信息内容。
