摘要： An aqueous dispersion of synthetic resin mutually dissolved with a cellulose acetate alkylate is prepared by mixing water, a protective colloid and/or a surfactant, a cellulose acetate alkylate, an oil-soluble radical polymerization initiator and at least one monomer in which the cellulose acetate alkylate and the oil-soluble radical polymerization initiator are soluble, under stirring, to form an aqueous dispersion and then subjecting the monomer to radical polymerization to form a homogeneous mixture of the cellulose acetate alkylate and at least one polymer in the particles in the aqueous dispersion.

摘要： The initiator composition is effectively used for a photopolymerizable resin composition which comprises a photopolymerizable compound having a double bond for polymerization and a polymer binder and comprises (A) thioxanthone or a substituted thioxanthone and (B) an oxime ester of the formula: ##STR1## wherein R.sub.1 and R.sub.2 may be the same or different and represent each an alkyl group having 1 to 10 carbon atoms, a substituted or unsubstituted phenyl, naphthyl, anthryl, pyridyl or quinolyl group or R.sub.1 and R.sub.2 may be bonded together to form a ring, and R.sub.3 represents an alkyl group having 1 to 5 carbon atoms or a substituted or unsubstituted aryl group.
