PURPOSE:To prevent the contamination of a PVC product and the staining of a duplicated image by using a compd. selected from a methacrylic acid, acrylic acid and their esters having a specific glass transition point. CONSTITUTION:A toner is costituted of a polymer A incorporated therein with one kind of compd. (a) selected from the group consisting of hydroxyalkyl methacrylate, hydroxy alkyl acrylate, acrylic acid, methacrylic acid, glycidyl methacrylate, glycidyl acrylate, methacrylonitrile, and acrylonitrile as a constituting component and a coloring agent B. The component A is the polymer in which 30-70wt% a styrene monomer or methyl methacrylate or both thereof and 10-30wt% one kind among alkyl methacrylate, alkyl acrylate, vinyl ester or vinyl ether are incorporated in addition to said compd. (a) at such a rate to make 100wt% total quantity. Such polymer has good thermal fixability and stability against moisture without sticking of vinyl chloride. |
