Abstract
A thermal transfer recording material comprising a support having thereon an image transferring layer containing a coloring material represented by Formula (I), Formula (I): wherein each R11 and R12 is independently a substituted or unsubstituted aliphatic group; R13 is a substituent and n is an integer of 0 to 4, provided that when n is 2 or more, a plurality of R13s are the same or different; R14 is an alkyl group; and each R15 and R16 is independently an alkyl group having 3 to 8 carbon atoms.
Claims6
A thermal transfer recording material comprising a support having thereon an image transferring layer containing a coloring material represented by Formula (II),
- wherein each R21 and R22 is independently a substituted or unsubstituted aliphatic group;
- R23 is a substituent and n is an integer of 0 to 4, provided that when n is 2 or more, a plurality of R23s are the same or different;
- R24 and R25 each are an alkyl group;
- R26 is a branched chain alkyl group;
- and R27 is an alkyl group other than methyl group.
A thermal transfer recording method, comprising the steps of:
- (a) superimposing an image receiving material onto a thermal transfer recording material comprising a support having thereon an image transferring layer containing a coloring material represented by Formula (II),
- (b) applying heat onto the thermal transfer recording material to form an image;
- and
- (c) separating the thermal transfer recording material and the image receiving material from each other,
- wherein each R21 and R22 is independently a substituted or unsubstituted aliphatic group;
- R23 is a substituent and n is an integer of 0 to 4, provided that when n is 2 or more, a plurality of R23s are the same or different;
- R24 and R15 each are an alkyl group;
- R26 is a branched chain alkyl group;
- and R27 is an alkyl group other than methyl group.
An ink for ink jet printing, which comprises a metal complex dye prepared from a compound containing a metal ion and a coloring material represented by (II)
- wherein each R21 and R22 is independently a substituted or unsubstituted aliphatic group;
- R23 is a substituent and n is an integer of 0 to 4, provided that when n is 2 or more, a plurality of R23s are the same or different;
- R24 and R25 each are an alkyl group;
- R26 is a branched chain alkyl group;
- and R27 is an alkyl group other than methyl group.
