A protecting film for covering a recording face of a recording medium includes a support, a first protective layer formed of thermoplastic resin and formed on the support, and a second protective layer formed of thermoplastic resin, and laminated on the first protective layer. An image is formed on the recording face by a thermal transfer type overcoat process.

A polarizer plate including a polarizer substrate formed of a polarizer layer and supporting layers disposed on opposite surfaces of the polarizer layer; an undercoat layer disposed on one surface of the polarizer substrate; an anti-reflection layer disposed on the undercoat layer; and an anti-staining layer including a fluorine-containing silane compound disposed on said anti-reflection layer. The undercoat layer preferably has a specular glossiness according to JIS Z 8741 of from 10 to 40 and a haze according to JIS K 6900 of from 5 to 30%.

An inorganic coating film having improved water repellency is provided. The improved surface is provided by treating an inorganic coating film with a material that is reached or adsorbed on the surface of the inorganic coat to increase water repellency. The inorganic coating to be treated may be a silicon dioxide film. The materials used to treat the film include: (1) halogenated silane compounds; (2) silane compounds having a structure including at least one bond selected from Si--H, Si--OH, Si--OR, Si--SH and Si--SR, wherein R is an organic group; (3) silane compounds having a structure including at least one of ##STR1## wherein R1, R2 and R3 are hydrogen or an organic group and (4) reactive organic compounds having a fluorine substituting group, hydrogen fluoride or a metal fluoride.

Electronic sunglasses of the transmittance-varying type including liquid crystal panels employing the electro-optical effect and a solar cell used as a power source. The electronic sunglasses include a voltage detecting circuit having such a hysteresis characteristic so as to output a signal for changing transmittance of the liquid crystal panel from a high mode to a low mode at at least high predetermined voltage or illumination, and changing transmittance from a low mode to a high mode at at least a low voltage or illumination. The sunglasses also include a first switch which operates at at least two switch positions, one switch position having a first stage of illumination at less than 20,000 Lux and a second stage of illumination at 20,000 Lux or greater at which transmittance is changed from a high mode and another switch position disabling the voltage detecting circuit. Also included is a second switch which operates to change transmittance from a high mode to a low mode independently of the set voltage value in the voltage detecting circuit according to the hysteresis effect.
