    • The invention provides a coating on a polymeric substrate forming a non-porous print receptive layer on the polymeric substrate, printability, thermal conductivity. Tg, surface hardness and surface smoothness of the print receptive layer being regulated by forming the print receptive layer from a dispersion containing a mixture of at least two acrylic latexes, at least one chosen to have an acid value of 20 to 60 mg KOH/g resin and a Tg less than 35 centigrade degrees, and at least one having a Tg greater than 90 centigrade degrees so as to adjust the hardness/Tg of the print receptive layer the acrylic polymer being present in each latex in the discontinuous phase so that the latexes are only partially miscible with one another, the dispersion further containing as essential components a metal containing cross linking agent to cross link the acrylic latexes and thereby further regulate both the thermal conductivity and the surface hardness of the print receptive layer, hollow polymeric particles to regulate the thermal conductivity of the print receptive layer and silica particles with a primary particle size of less than 100 nm to regulate the surface smoothness of the print receptive layer.
    • 本发明提供了在聚合物基材上形成在聚合物基材上的无孔印刷接收层的涂层,可印刷性,导热性。 通过从包含至少两种丙烯酸胶乳的混合物的分散体形成印刷接受层来调节印刷接受层的Tg,表面硬度和表面平滑度,至少一种选自具有20至60mg KOH / g酸值 树脂,Tg小于35摄氏度,Tg至少为90摄氏度以上的至少一种,以便调节不连续相中每个胶乳中存在的丙烯酸类聚合物的印刷接受层的硬度/ Tg,使得 胶乳仅相互部分混溶,分散体还含有作为必需组分的金属含交联剂以交联丙烯酸胶乳,从而进一步调节印刷接收层的热导率和表面硬度,中空聚合物颗粒至 调节印刷接受层和一次粒径小于100nm的二氧化硅颗粒的热导率以调节s 打印接受层的表面平滑度。
