摘要： An object is to provide a transfer film that can impart sufficient durability such as abrasion resistance and solvent resistance to a transfer object surface and has high transfer property without causing any transfer failures such as tailing and burr. The transfer film according to the present invention comprises a substrate and a protective layer peelably provided on the substrate, wherein the protective layer comprises an active ray-cured resin and a filler; wherein the active ray-cured resin contains polyfunctional urethane (meth)acrylate as a polymerization component; and wherein the filler has a volume average particle size of 40 nm or less.

摘要： The purpose of the present invention is to provide a thermal transfer sheet which can prevent a kick and a scumming, and can form a photographic tone color image of high quality with a continuous tone image by sublimation transfer, while expanding the range of choices for colorants to be included in a colorant layer; a coating liquid for colorant layer to be used for forming the colorant layer of this thermal transfer sheet; a method for manufacturing this thermal transfer sheet; and image forming method employing this thermal transfer sheet. The problem is solved by a thermal transfer sheet (1) in which at least a colorant layer (3) is layered on a substrate sheet (2), wherein the colorant layer (3) contains a predetermined solvent, a colorant (10x) dispersible in the predetermined solvent, a dispersant, and a binder resin, and the dispersant being one or more selected from the group consisting of polyether-based dispersants, graft type polymer dispersants, acryl-based block type polymer dispersants, urethane-based polymer dispersants and azo-based dispersants.
