Title:
IMAGE RETRANSFER SHEET
Document Type and Number:
Japanese Patent JP3715734
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To easily retransfer an image to a secondary transfer material and also to obtain good paper feeding/carrying characteristics in an electrophotographic copying device by controlling a surface roughness within a specified extent, as for an image retransfer sheet provided with a covering layer containing thermoplastic resin.
SOLUTION: The image retransfer sheet 1 is constituted by successively laminating a strippable layer 3 and a covering layer 4 on a substrate 2. And the surface roughness 8 of the covering layer 4 is regurated to be 3 to 10μm, and in the case of controlling the surface roughness 8 within the aforesaid extent, the good paper feeding/carrying characteristics and the good retransfer are accomplished. That is, in the case the surface roughness is <3μm, the surface is too smooth to cause defective carrying, that is, the transfer material sticking to a transfer drum in the electrophotographic copying device sticks to a photoreceptor drum only with a slight contact with the photoreceptor drum. Contrarily, in the case the surface roughness 8 is ≥10μm, defective transfer occurs when the solid image is formed. And also, the surface is too rough to transfer the sheet to the transfer material side at the time of retransferring.
