Abstract
Abstract An image-forming process using a long rolled transparent light-sensitive recording material is disclosed. The process comprises applying at least two image-forming steps each including at least an image exposure and a development to a long rolled transparent light-sensitive recording material comprising a support having thereon a light-sensitive layer and a surface protective layer containing a hardenable compound and fine particles. The recording material preferably has a backing layer containing fine particles.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
149 words
An image-forming process which comprises applying a least two image-forming steps each including at least an image exposure and a development to a long rolled transparent light-sensitive recording material comprising a support having on one surface a light-sensitive layer and a surface protective layer having a thickness of from 0.01 to 20 μm and on another surface a backing layer having a thickness of from 0.01 to 20 μm, wherein said surface protective layer contains at least one of fine particles having a mean particle size in the range of from 0.005 to 5 μm and a hardenable compound and said backup layer contains fine particles having a mean particle size in the range of from 0.005 to 5 μm, and wherein the transparent light-sensitive recording material is an electrophotographic recording material wherein the support is an electrically conductive support and the light-sensitive layer is an electrophotographic light-sensitive layer.
Claim 2
Dependent Claim
149 words
An image-forming process which comprises applying a least two image-forming steps each including at least an image exposure and a development to a long rolled transparent light-sensitive recording material comprising a support having on one surface a light-sensitive layer and a surface protective layer having a thickness of from 0.01 to 20 μm and on another surface a backing layer having a thickness of from 0.01 to 20 μm, wherein said surface protective layer contains at least one of fine particles having a mean particle size in the range of from 0.005 to 5 μm and a hardenable compound and said backup layer contains fine particles having a mean particle size in the range of from 0.005 to 5 μm, and wherein the transparent light-sensitive recording material is an electrophotographic recording material wherein the support is an electrically conductive support and the light-sensitive layer is an electrophotographic light-sensitive layer.
