PURPOSE:To eliminate density unevenness (void) by a method wherein a receptor layer is made of a composition which consists of a specified quantity of polyolefin and a specified quantity of rosin group or rosin ester group. CONSTITUTION:Rosin group and rosin ester group (referred to as modified resins hereafter) are non-poisonous and their compatibility to polyolefin is also favorable. Especially, colorless rosin, and colorless rosin ester are superior in heat resistance, weathering resistance and resistance to oxidation, etc. A polyolefin composition which constitutes an image receptor layer is obtained by blending two components, polyolefin and a modified resin, by respective specified quantities. The usage rate of polyolefin in the composition is appropriately determined from viewpoints that the image receptor layer has favorable adhesive properties with an ink sheet, and also the image receptor layer can be easily released from the ink sheet, and normally, it is 75-98wt.% in the image receptor layer, and preferably is 85-95wt.%. Also, the usage rate of the modified resin is 2-25wt.%, and preferably is 5-15wt.%. |
