摘要: 本文研究了由无色结晶紫(LCV)和CBr4组成的自由基光敏片的红光显影特性.提出用图像强化系数Kmax作为光显影效果定量表征参数,研究了光波长对光显影效果的影响,并对光显影中的诱导期作了解释,认为主要是氧的存在引起的.

Abstract: A quantitative characterization parameter in. optical development of free radical photography Kmax is proposed and its significance and method of measurement are elucidated. Effects of the wavelength (used) on the optical development of Leuco crystal violet/CBr4 film and the effects of the adhesive medium and temperature on the rate of optical development have been studied. The activation energy is estimated at about 10kcal/mole.
The induction period of optical development has also been interpreted. There are two different processes in optical development. In the induction period oxygen quenching of the excited dye molecules by the diffusion-control predominates while in the main period of the reaction energy transfer-control photochemical reaction predominates.
