    • Disclosed is a process for preparing a colored polymer without color change between a reactant color dye and an obtained polymer. The process of the present invention comprises polymerizing a vinyl polymerizable monomer (A), and a polymerizable dye (B) prepared by reacting a (meth)acryloyl compound having a group reactive with an active hydrogen, with a dye represented by the formula: ##STR1## wherein R.sub.1 and R.sub.2, which are the same or different, show a hydrogen atom or a group having the formula; ##STR2## (R.sub.3 represents --(CH.sub.2)m-NH.sub.2, or --(CH.sub.2)m-OH, R.sub.4 represents a hydrogen atom, an alkyl group, a cycloalkyl group or an allyl group, n is an integer of 1 to 5 and m is 0 or an integer of 1 to 5), provided that both R.sub.1 and R.sub.2 do not represents a hydrogen atom, X and Y, which are different, --OH or --NHR.sub.1,in the presence of a polymerization initiator, and a color difference between the polymerizable dye and the obtained colored vinyl polymer is within .+-. 3 nm by absorption spectrum.
