  Abstract

Polyglyceryl phthalate, bisphenol A-epichlorohydrin 축중합물 및 polyvinyl alcohol의 naphthoquinone-1,2-diazide-5-sulfonyl esters(PGND, BEND 및 PVAND)에 대해 미증감 및 증감한 경우의 IR 스펙트럼을 측정하여 그들의 광분해기구를 연구하였다. o-quinonediazide에 기인하는 C=N= 및 C=0의 흡수가 노광에 의해 감소내지는 소실하고있었고 또한 indene carboxylic acid의 C=0 흡수강도가 증가되고 있는 것으로 보아 o-quinonediazide group 이 광에 의하여 분해하여 알카리 수용액에 가용성인 indene carboxylic acid로 분해되는 것으로 추정된다. 한편, 노광시간에 대한 증감 및 미증감시료의 흡수광도의 변화를 측정하므로서 증감제의 증감효과도 아울러 검토하였다. The degradation mechanisms of naphthoquinone-1,2-diazide-5-sulfonyl esters(PGND, BEND and PVAND) of polyglyceryl phthalate (PG), bisphenol A-epichlorohydrin (BE) and polyvinyl alcohol (PVA) were studied by infrared absorption spectra. Absorption band due to C=N=and C=O of o-quinonediazide group decreased or disappeared after sufficient exposing to light. And also, absorption band C=O of indene carboxylic acid was increased. From the results, it may be concluded that the above photosensi tive polymers were dissociated to indene carboxylic acid soluble in aqueous alkali solution. Further, the effect of sensitizers were examined by the variation of intensity in infrared absorption spectra of sensitized and unsensitized samples.
