    摘要: This invention relates to hydroxyalkylated chitosan solution characterized in that a hydroxyalkylated chitosan and an organic acid or its derivative are contained in an aprotic polar solvent. This invention also relates to a coating process of a substrate, which is characterized by a step of causing the hydroxyalkylated chitosan solution to adhere onto a surface of the substrate, and another step of heating the substrate, which has been obtained in the first-mentioned step, at 100° C. or higher for 1 second or longer. This invention can provide a one-pack solution of a chitosan derivative, which is free from crosslinking and stable at room temperature, can form a chitosan coating excellent in waterproofness after heated and dried, and is suited for the coating of a hydrophobic or lipophilic surface. This invention also provides a coating process of a substrate, which makes use of the one-pack solution.

    摘要: A colored polyamide fiber composed of a polyamide resin, a pigment, a coupling agent and a compound represented by the following formula I: R′—CO—NH—R—NH—CO—R″  (I) wherein R is an alkylene group having 1 to 4 carbon atoms, and R′ and R″ are each independently an aliphatic hydrocarbon group having 9 to 18 carbon atoms. The colored polyamide fibers are produced without causing bending and fiber break during the melt spinning even when the raw composition contains the pigment in a high concentration. Since the pigment is uniformly dispersed throughout the colored polyamide fibers, the coloration is deep and the strength is high. The colored polyamide fibers are suitable for the production of artificial leathers.

    摘要: An optical deflection apparatus includes a signal light source configured to emit signal light having one or more wavelengths, a control light source configured to emit control light having a wavelength different from the wavelength of the signal light, a thermal lens forming optical element including a light absorption layer configured to transmit the signal light and selectively absorb the control light, and a beam-condensing unit configured to cause beam-condensation of the control light and the signal light at different convergence points in the light absorption layer. The thermal lens forming optical element causes convergence and divergence of the control light and the signal light on an incidence plane of the light absorption layer or its vicinity in a light traveling direction, wherein a thermal lens is reversibly formed in the light absorption layer due to a temperature increase occurring in a region where the control light is absorbed and its peripheral region, and the thermal lens changes a refractive index to change a traveling direction of the signal light.
