发明名称 SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL
摘要 PURPOSE:To obtain a silver halide photographic sensitive material which is improved in the haze during long-term storage and has excellent bright discolorability by incorporating polverous particle powder having 1-10mum average grain size into the outermost layer among non-photosensitive layers and mixedly incorporating >=2 kinds of specific UV absorbents into at least one layer of the remaining non-photosensitive layers. CONSTITUTION:The silver halide photographic sensitive material has >=2 non- photosensitive layers on the silver halide emulsion layer furthest from a base when viewed from the base on the side opposite from the base side. Said material has such constitution that the outermost layer of the non-photosensitive layers contains the pulverous particle having 1-10mum average grain size and at least one layer of the remaining non-photosensitive layers mixedly contains >=2 kinds of the UV absorbents expressed by the formula. The halogen atoms expressed by R1-R3 in the formula are exemplified by a fluorine atom, chlorine atom and bromine atom, etc. and are more particularly preferably the chlorine atom. The alkyl group and alkoxy group expressed by R1-R3 are preferably of 1-20 C and the alkenyl group is preferably of 2-20 C.
