ABSTRACT:
A donor film for a color filter is provided. The donor film includes a support layer, a light absorbing layer and a transfer layer, wherein the transfer layer comprises an acryl resin represented by the following formula (1) as a bonding resin: ##STR1## where R.sub.1 indicates a hydrogen or methyl group; R.sub.2 indicates C.sub.1 .about.C.sub.12 alkyl, C.sub.2 .about.C.sub.10 hydroxyalkyl, substituted or unsubstituted aromatic ring, C.sub.5 .about.C.sub.10 cycloalkyl or benzyl group; R.sub.3 indicates C.sub.1 -C.sub.12 alkyl, substituted or unsubstituted aromatic ring, C.sub.5 .about.C.sub.10 cycloalkyl or benzyl group; X indicates a vinyl group, epoxy group or hydrogen atom; and 0.1.ltoreq.a.ltoreq.0.65, 0.3.ltoreq.b.ltoreq.0.8 and 0.ltoreq.c.ltoreq.0.2 (Here, a, b and c denote mole fractions, and the sum of a, b and c is 1). According to the manufacturing process of a color filter using a donor film of the present invention, only transfer and curing processes are required for each color, and also the color layers may be cured all at once, if necessary, to thereby largely reduce the number of processes. Thus, the color filter using the donor film is easily manufactured.
