摘　　要：本文简要介绍了高聚物P1的合成方法以及在黑白相纸中的应用试验，探讨了其作用机理。试验证明：高聚物P1在黑白相纸中具有一定的增感增黑作用，对于降低相纸的涂布银量和减薄涂层厚度；降低光谱增感染料用量，从而减轻染料对乳剂的染色作用，提高相纸的画面白度以及改善乳剂膜的物理性能等方面具有显著的效果。This paper presents a report on the method for synthesizing high polymer P1 and test results of its use in b/w photographic paper, together with some discussion on its behavior mechanism. It was shown that the hi-polymer P1 has a definite sensitizing and blackening effect,thus decreasing the silver coating weight and layer thickness of b/w photographic paper ; the dose of dye for spectral sensitizing dye can be reduced,thus reducing the staining of the emulsion by the dye and improving the picture whiteness; the physical properties of the emulsion layer are also improved.
