(wherein R.sub.1 to R.sub.4 each independently represent an alkyl group or the like; R.sub.5 to R.sub.7 each independently represent a hydrogen atom or a methyl group; n pieces of R.sub.8 each independently represent a halogen atom, an alkyl group, an aryl group, a hydroxy group, a nitro group, a sulfo group, an alkoxy group, or the like; and n represents an integer of 0 to 4. A.sub.1 represents an alkylene group, or the like; A.sub.2 represents NH or O. An.sup. represents an anion containing an aryl group having an electron-withdrawing substituent, a sulfonyl group having an electron-withdrawing substituent, or a halogenated alkyl group.)

A violet blue gradient color, blue light resistant and full-screen tempered privacy screen protector, comprising an electroplated oleophobic layer, a diamond explosion-proof layer, a tempered coating, a flexible explosion-proof layer, a silk screen reinforcing layer, a composite violet blue gradient and blue light resistant layer and a privacy protection layer, wherein the composite violet blue gradient and blue light resistant layer comprises a violet blue gradient film and a blue light resistant film. By the nanotechnology used in the present invention, existing spy-proof layers can be coated to be violet blue gradient and blue light resistant layers, and compared with the prior art, the blue light resistant layers can be coated more efficiently and rapidly, so that a plurality of layers are integrated with high efficiencies and yield. The composite violet blue gradient and blue light resistant privacy layer has integrated refraction effects on the basis of existing louver technologies.
