METHOD FOR THERMAL DEVELOPMENT OF PHOTOSENSITIVE ELEMENT USING DEVELOPMENT MEDIUM HAVING SUPPORT

摘要

PROBLEM TO BE SOLVED: To provide a method for thermally developing a photosensitive element to form a relief pattern.

SOLUTION: The method includes a step of heating a composition layer of the photosensitive element to cause a portion of the composition layer to liquefy, and a step of providing a development medium under tension to the photosensitive element to absorb the liquefied composition. The development medium includes an absorbent material and a support, the combination of which minimizes stretch and distortion of the absorbent material and can impede the migration of the liquefied composition through the absorbent material.
