Abstract:
A backprinting recording medium, comprising a transparent substrate, an ink-absorbing layer formed on the transparent substrate and a porous ink-permeable layer formed on the ink-absorbing layer, wherein said porous ink-permeable layer produced by dispersing a filler in a binder resin, wherein:the binder resin includes a first polyester resin and a second polyester resin, the resins being present in a ratio of from 1:1 to 7:3 of the first polyester resin to the second polyester resin; the first polyester resin has a glass transition temperature of from 35Â° C. to 80Â° C. and a Shore D hardness at 25Â° C. of from 60 to 80; the second polyester resin has a glass transition temperature of less than 35Â° C. and a Shore D hardness at 25Â° C. of less than 60; and the binder resin has a glass transition temperature of 23.1Â° C. to 41.2Â° C., and a Shore D hardness at 25Â° C. of from 50 to 62.
