Abstract
The present invention relates to an adhesive composition utilized to adhere an ink layer to a first substrate of a recording medium used for heat-sensitive transfer printing. The adhesive composition comprises polyamide and organo boron polymer. The organo boron polymer is a polyester which includes acidic chelate complex residue by reaction of polyol and boric acid. The adhesive composition provides a sufficient adhesive force between the ink layer and the first substrate of the recording medium such that the ink layer does not peel off from the first substrate and stick to a dye acceptor layer of a second substrate during the heat-sensitive transfer printing process.
