    摘要： A scraping sealing device for cleaning the stems and the bristles of liquid or pasty cosmetic product applicators, comprising a substantially cylindrical body of flexible material, crossed by an axial hole, to be applied to the neck of a container; the body showing a terminal section having a substantially truncated conical layout, wherein the outer wall of the terminal section, which reaches the applicator, forms with the device axis an angle different from 90 degrees, the device wall tapering in the terminal section until null thickness at the the edge is encountered.The device makes an exhaustive cleaning of the stem when the latter is extracted from the bottle. It completely removes the exceeding contents present on the bristles and when the applicator is again inserted into the bottle, the device makes an efficacious hydraulic seal around the stem body, that avoids the product from drying.

    摘要： Organic electron donor compounds for use in electrophotographic constructions must ordinarily be sensitized to desired regions of the electromagnetic spectrum. Indolenine dyes having phenylsulfonyl or benzoyl substituents thereon have been found to be efficient sensitizers, particularly in the infrared portion of the electromagnetic spectrum, for such organic donor compounds.

    摘要： It is desirable to protect color photographic dye images from ultraviolet radiation which tends to cause dyes to fade.It has been the practice in the art to add materials into or above the silver halide emulsions which will absorb ultraviolet radiation but allow transmission of visible radiation.One of the best classes of compounds are the 2-(2'-hydroxyphenyl)-benzotriazoles. These materials absorb ultraviolet radiation well, but tend to have poor solubility, crystallize out of the coating solution and emulsion, and diffuse through the photographic element.A novel class of substituted 2-(2'-hydroxyphenyl)-benzotriazoles has been found to reduce many of these problems.
