PAPER-MADE WINDING CORE FOR SENSITIVE MATERIAL SUBJECTED TO MELT TRANSFER BY LIGHT EXPOSURE, AND ROLL-LIKE SENSITIVE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a paper-made winding core and roll-like sensitive material capable of preventing an embossing that is a problem caused in the winding of a sensitive material subjected to melt transfer by light exposure on a winding core in roll shape and excellent in environmental adaptability. SOLUTION: This paper-made winding core for winding the sensitive material subjected to melt transfer by light exposure in roll shape comprises a plurality of paper layers 2 laminated on the surface of a winding core body 100. Each of the paper layers 2 is formed of a cushioning paper, the density thereof is reduced toward an outermost layer 21, and the density of the outermost layer 21 is 0.1 g/cm3 or less. In this roll-like sensitive material formed by winding the sensitive material subjected to melt transfer by light exposure on the winding core in roll shape, the terminal end of the sensitive material is bonded to the winding core by use of an adhesive tape, and the adhesive tape is stuck out of the lateral effective angle of view in the terminal end of the sensitive material.
