PURPOSE:To improve the moisture resistance by forming a protective layer contg. a specified butyl etherified melamine-formaldehyde resin and a specified alkyl etherified benzoquanamine-formaldehyde resin. CONSTITUTION:A protective layer contg. a cured film contg. a butyl etherified melamine-formaldeyde resin having <=1,500 number average mol. wt., 2-4 formaldehyde groups and 1-2 methylol groups bonded to one melamine nucleus and an alkyl etherified genzoguanamine-formaldehyde resin having 400-2,000 number average mol. wt. is formed one the surface of a photosensitive layer. Thus, the moisture resistance of the resulting sensitive body is improved.
