PURPOSE:To provide a photosensitive material which has good heat developability and dye permeability and is free from uneven transfer by incorporating a polymer having the repeating unit expressed by specific formula therein. CONSTITUTION:The preferable polymer to be used is the homopolymer consisting of one kind of the repeating unit expressed by (formula) and is more preferably the homopolymer of which R in the (formula) is an alkyl group of 1-4C. R is preferably an ethyl group, for which a polyethyl oxazoline is effective. The polyoxazoline polymer having excellent compatibility with gelatin, etc., is incorporated into an intermediate layer to be provided between the binder of the photosensitive layer and the photosensitive layer or a protective film, etc., in the above-mentioned manner, by which the heat developable photosensitive material having excellent coating property in the stage of production is obtd. |
