PURPOSE:To prevent staining of a non-image part at the time of printing by forming an intermediate layer of a compd. selected from compds. having an amino group and hydroxyl group and the salts thereof. CONSTITUTION:The intermediate layer is formed on the compd. selected from the compds. having at least one amino group and at least one hydroxyl group and the salts thereof. Such compd. is adequately the compd. having <=1,000mol. wt., for which, for example, monoethanol amine, diethanol amine, trimethanol amine, tripropanol amine, triethanol amine and the hydrochloride, oxalate and phosphate thereof are useful; above all, the triethanol amine and triethanol amine hydrochloride are most preferable. The staining in the non-image part at the time of printing is thereby prevented. |
