Abstract
PURPOSE:To obtain the titled material of high printing durability and low cost and furnished with a roughened surface of a resin layer by applying high density polyethylene both to a print picture forming layer of a support object having a polyethylene resin coating layer on both sides of a paper-base and to a polyethylene resin layer of the opposite side. CONSTITUTION:As for a planoghraphic material furnished with a print picture forming layer on a support object coated with a polyethylene resin (preferably that of specific gravity 0.926 or over) to a polyethylene resin layer on the opposite side of the one having the print picture forming layer, and by roughening this polyethylene resin layer surface, an object material is made. Furthermore, as for applying the high density polyethylene, that of specific gravity 0.941 or over by 40-90wt% is desirable. Also, the desirable condition of the roughened surface is such that its depth is 2-20mu, and the distance between a crest to another is 10-100mu.
