Title:
IMAGE REMOVAL ACCELERATING LIQUID AND METHOD FOR REGENERATING MATERIAL TO BE RECORDED BY USING THE IMAGE REMOVAL ACCELERATING LIQUID
Document Type and Number:
Japanese Patent JP3501438
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To sufficiently peel and remove hydrophobic images from a material to be recorded, to obviate the occurrence of elongation, wrinkles, waving or curling, etc., in the material to be recorded and to lower dyed residual image density by constituting an image removal accelerating liquid of an aq. soln., hydrous org. soln. or anhydrous org. soln. contg. a surfactant, oxalic acid and urea based compd. and/or thiourea compd.
SOLUTION: The image removal accelerating liquid consisting of the aq. soln., hydrous org. soln. or anhydrous org. soln. contg. the surfactant, the oxalic acid and the urea based compd. and/or thiourea compd. is used. In the case of, for example, the aq. soln., the soln. is obtd. by adding and dissolving the surfactant, the oxalic acid and the urea based compd. and/or thiourea compd. into water or an org. solvent contg. the water. In the case of the anhydrous org. soln., the soln. is obtd. by adding and dissolving the surfactant, the oxalic acid and the urea based compd. and/or thiourea compd. into an anhydrous org. solvent. Then, the hydrophobic images are sufficiently removed and the elongation, wrinkles, etc., are eliminated.
