  A modified gelatin is disclosed wherein part of the free carboxyl groups is replaced by modifiers having more acid end-standing groups chosen from -SO₃M, -OSO₃M, -SSO₃M, -OPO(OH)₂, - OPO(OH)(OR²), -PO(OH)₂, -PO(OH)(OR²). In a preferred embodiment such a modified gelatin is incorporated in a DTR photographic material which after processing can serve as a lithographic printing plate. Thanks to the more hydrophilic character of the modified gelatin the differentiation between printing and non-printing areas is improved and toning at printing start-up is reduced.

  本发明公开了一种改性明胶，其中部分游离羧基被具有更多酸性末端基团的改性剂所取代，这些改性剂选自-SO₃M、-OSO₃M、-SSO₃M、-OPO(OH)₂、-OPO(OH)(OR²)、-PO(OH)₂、-PO(OH)(OR²)。 在一个优选的实施方案中，这种改性明胶被加入到 DTR 感光材料中，经过处理后可用作平版印刷板。由于改性明胶具有更强的亲水性，印刷区域和非印刷区域之间的区分得到了改善，印刷启动时的色调也得到了减少。
