The results of investigation of the phenomena ISPh was reported. It was shown that in the given layers after the
irradiation of the polarized light with wave-length actinic for the given sensitizer and of the following specific
development the photo-induced anisotropy was visualized. It turns out that weakly expressed anisotropy of the latent
image multiplied more than on the two order of magnitude. As it was shown in this investigation, the value of the photo
anisotropic parameters can changed in wide-ranging after the specific physicochemical treatment: hypersensitizing,
specific worked out developers, thermal treatment, fixing (in case of need). Each of the procedure has such essential
value, that the separated examination was needed. For example, 20 developing agent per se and large quantity of the
different compositions, and also the quantity hypersensitizers was investigated. The photo induced anisotropy maybe
measured on the modified spectrophotometers SF-10 or SF-18. To receive experimentally the dependence of the
anisotropic absorption, and the light induced birefringence it is necessary to carry out not less than 6 measurements of
transmission of the differently oriented irradiated samples (0°; 45°; 90°), placed between parallel and crossed polarizers
in the spectrophotometer. Some technological regimes which reduced to the optimization of the parameters of the photo
anisotropy are presented. The high stability, the possibility of working in the red region and with the low power energy
sources, with the wide controlled characteristics are represented the main advantage of such media. In addition the
Schwarzchild effect in the ISPh phenomena is considered.
Azo indicators are well known in which when changing acidity they changes their properties. It was natural to expect
also their appreciable changes of their polarization properties. The results of the carried out experimental research in
recording media on the basis of azo indicators- homolog of the Methyl orange introduced into the polymeric matrix are
presented in this work. According to the technology developed by us, the samples for the reception of which solvents
with various degree of acidity, within values pH 1.68-12.45 have been created. Samples were irradiated by the light of
argon laser (488 nm) actinic for them. Measurement of light induced anisotropy was carried out on a registering recorder
and can be described by means of one parameter- the effective anisotropy. As standards the samples of dyes for the
reception of which neutral solvent was used have been considered. In a number of dyes the values of effective anisotropy
in alkaline and acid media exceed its values concerning corresponding standards. The higher homolog -Heptyl orange
and Benzyl orange which are weak or insoluble in water, become water-soluble when using solvents both with acid and
alkaline reaction. The interval of appearance of light induced anisotropy has been expanded. We have used the method of
the zero-ellipsometry for the research arising in the same samples light induced gyrotropy. Values of circular dichroism
and circular birefringence in investigated layers in neutral media have been calculated also at various values pH. In the
work the received results are discussed and analyzed.
In this article the results of experimental investigations of photo anisotropy in organic dyes embedded in different
polymer matrices are reported. All the matrices used in this work can be subdivided into those entering into a chemical
reaction with dye molecules and those that are chemically inactive. The results of this investigation are suggested that the
matrix is of crucial importance of the creation of photo anisotropic materials.
