Abstract: An adhesive for a polarizer is described, and is made of a solution of polyvinyl alcohol and an aldehyde. A catalyst may be further added therein. Additionally, glyoxal may be selected as the aldehyde, with a content preferably around 0.01% to around 5% by weight. On the other hand, the concentration of the polyvinyl alcohol aqueous solution is preferably about 1% to about 10% by weight.

Abstract: A novel design and usage of sanitary article for advising personally physiological condition includes a detection zone or testing zone, a coating strip or polymer material, which is imbedded into and disposed on the sanitary article, to reveal the assigned physiological advisement. The secretions or menses remained on the sanitary article reacts with the detection zone or testing zone and displays the health condition of the user thereon. Accordingly, the user of the sanitary article can advice personally health condition as preventative diagnostics.

Abstract: A light-polarizing film with high permeability for improving an interference light of a color organic light emitting diode (OLED), wherein a phase retardation plate is disposed on the color OLED for transforming light phase, and the light-polarizing film is disposed on the phase retardation plate for absorbing the projective light. The polarization degree of the light-polarizing film is between 15% and 93%, the corresponding permeability is between 46% and 80%, whereby the light-polarizing film with high permeability is utilizes to acquire necessary light-polarizing effect of emitting light of the color OLED itself, the color OLED doesn't need to increase power, and the color OLED can keep original economical lifetime.
