| titleOfInvention | A thermal sensitive recording sheet |
| abstract | A thermally sensitive recording sheet which comprises on a substrate, a thermally sensitive colour developing layer comprising:n (a) a colourless or pale coloured basic leuco dye; (b) an organic colour developer of formula (I):n wherein A is hydrogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, hydroxy or nitro, each of R 1 , R 2 and R 3 , which may be the same or different, is hydrogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, hydroxy or nitro, or R 1 and R 2 form, together with the carbon atoms to which they are attached, an aromatic ring, and Y is sulfur or oxygen; nor an organic colour developer of formula (II):n wherein B is hydrogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, hydroxy or nitro, each of R 1 , R 2 and R 3 , which may be the same or different, is hydrogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, hydroxy or nitro, or R 1 and R 2 form, together with the carbon atoms to which they are attached, an aromatic ring, and Y is sulfur or oxygen; and (c) 0.01-2 parts, based on 1 part of colour developer of formula (I) or (II), of a stabiliser which is a diphenylsulfone derivative of formula (III): |
