Abstract: An aspect of the present invention relates to a cosmetic laminate sheet including a thin film sheet that has a thickness of 10 nm or more and 10 ?m or less and is water-permeable and a support that has water absorbing properties and a possible amount of water content in the support being 4.4 g or more per 1 g of the support.

Abstract: Provided is a jig which assists in the adhesion of a thin-film sheet to an adhesion target surface (skin etc.), and which can easily adhere the thin-film sheet to the adhesion target surface. The jig includes: a base part having a first surface; and a porous hydrophilic film that is adhered to the first surface and has fine pores with a predetermined porosity, wherein the porosity is 35% to 55% inclusive. The hardness of the base part is preferably 4-20 inclusive. In addition, it is preferable that the base part and the hydrophilic film have transparency.

Abstract: Provided is an electrophotographic photoreceptor including a conductive support, a photosensitive layer, and a surface protective layer disposed in sequence. The surface protective layer includes a cured product of a composition containing a polymerizable compound, a charge transporting material, and at least two polymerization initiators. The polymerization initiators include an acyl phosphine oxide and an O-acyl oxime.

Abstract: An electrophotographic photoconductor (photoconductor) according to the embodiment includes a conductive support, a photosensitive layer, and a protective layer. The protective layer is composed of a cured product as one body obtained by a radical reaction of a composition containing a radical polymerizable monomer having a radical polymerizable functional group, a metal oxide fine particle having a radical polymerizable functional group, and camphorquinone or a derivative thereof. The photoconductor is installed in an image forming apparatus equipped with a cleaning device for removing transfer residual toner on the photoconductor, and the cleaning device includes an elastic cleaning member disposed so that it can come into contact with the surface of the photoconductor.

Abstract: This invention discloses and claims a series of polycyclic monomers and polymers useful in the production of optical waveguides. The polymers of the invention comprise one or more repeating units represented by the formula (IV): Wherein m, X, R1 and R2 are as defined herein. The films formed from the polymers of this invention exhibit significant changes in refractive index (greater than or equal to 0.5%) after exposure to suitable actinic or thermal energy thereby having superior optical transmission performance, which is of importance for modern optical applications such as wave guiding and optical data storage.
