  The relationship between the structures and absorption spectra of cyan color indoaniline dyes

  摘要：

  The absorption spectra of 23 indoaniline dyes were calculated on the AM1-optimized structures by means of the INDO/S method. The observed and calculated absorption wavelengths showed good correlation for the main (longest wavelength) absorption bands (observed at 560-670 nm), and there was fair correlation between the observed molar extinction coefficients and the calculated oscillator strengths. The observed absorption wavelengths could be reproduced by the calculation for the subabsorption bands near the visible region (observed at 320-380 nm). A qualitative correlation of the solvatochromic shift with the difference between ground and excited state dipole moments was obtained.

  [EN] The present invention provides novel hydrosilation-curable compositions, the cure of which can be monitored visually, comprising: (1) an ethylenic compound; (2) a compound containing silicon-bonded-hydrogen groups; (3) a hydrosilation catalyst; and (4) one or more cure-indicating dyes with light absorption in the visible spectrum that exhibit a color change in the presence of a silicon-bonded-hydrogen compound and a precious metal hydrosilation catalyst. The cure-indicating dye provides the composition with an initial pre-cure color and a different post-cure color. As a result of this change in color, the state of cure of the composition can be visually monitored.
  [FR] La présente invention concerne de nouvelles compositions polymérisables par hydrosilylation, dont la polymérisation peut être contrôlée visuellement, et comprenant: (1) un composé éthylénique; (2) un composé contenant des groupes hydrogène à liaison silicium; (3) un catalyseur d'hydrosilylation; et (4) un ou plusieurs colorants révélant la polymérisation, absorbant la lumière dans le spectre visible et présentant un changement de teinte en présence d'un composé hydrogène à liaison silicium et d'un catalyseur d'hydrosilylation en métal précieux. Le colorant révélant la polymérisation confère à la composition une teinte initiale avant polymérisation et une teinte différente après polymérisation. Ce changement de teinte permet de contrôler visuellement l'état de polymérisation de la composition.
