发明名称 Photographic polyolefin coated base papers and method of making
摘要 Polyolefin coated photographic base papers are stabilized by a polymeric hindered amine (Chimassorb 944) having a mean molecular weight above 2500. The stabilizer is highly effective and overcomes a diminution of opacity noted with the use of phosphonate esters of the prior art.
