PURPOSE:To produce printed matters with less runs, superior abrasion resistance and chemical resistance by roviding two stage heat treatment of heat drying and heating to a molded product of polyolefin group resin composite which was directly printed and by sublimating printed disperse dyestuff to infiltrate into the molded product. CONSTITUTION:Directly on the surface of a molded product made of polyolefin group resin composite a printing is performed with disperse dyestuff of pulverized powder in a paste form, using a bud printing machine or silk printing machine preferably with the etching depth of 10-20mum. Subsequently, the molded product is heat dried, preferably at 80-95 deg.C for 2-10min as a pretreatment and a heat treatment is provided, preferably at 120-160 deg.C for 2-10min and printed disperse dyestuff is sublimated from the surface of the molded product and infiltrated. Additionally, if chemical compounds of ester group and/or inorganic filler are mixed in the above stated resin composite, the infiltrating property of the dyestuff and security is improved, resulting in a satisfaction. |
