Abstract
A reversible heat-sensitive recording medium comprising a reversible heat-sensitive recording layer containing a resin matrix and an organic low molecular weight material, and an overcoat layer, wherein an intermediate layer comprising an ultraviolet ray-crosslinkable or electron beam-crosslinkable resin as a main component is provided between the reversible heat-sensitive recording layer and the overcoat layer.
Claims14
A reversible heat-sensitive recording medium comprising a reversible heat-sensitive recording layer containing a resin matrix and an organic low molecular weight material, and an overcoat layer, wherein an intermediate layer comprising an ultraviolet ray-crosslinkable or electron beam-reversible heat-sensitive recording layer and the overcoat layer;
- wherein said ultraviolet ray-crosslinkable or electron beam-crosslinkable resin comprises:
- (A) an oligomer, and
- (B) a di(meth)acrylate monomer containing a long-chain alkylene group having from 4 to 10 carbon atoms in one molecule;
- and
- wherein the (A)/(B) weight ratio is from 90/10 to 10/90.
