Abstract

A polycarbonate resin molding comprising a polycarbonate resin composition, wherein the polycarbonate resin composition comprises: a polycarbonate resin; at least one of an ultraviolet absorber and a fluorescent whitening agent; a hindered amine; and a hindered phenol, wherein the polycarbonate resin molding has a light transmittance of 0.1% or lower in a wavelength of not longer than 410 nm, and a lamp cover comprising the resin molding.

Claims (30)

1 . A polycarbonate resin molding comprising a polycarbonate resin composition,

wherein the polycarbonate resin composition comprises: a polycarbonate resin; at least one of an ultraviolet absorber and a fluorescent whitening agent; a hindered amine; and a hindered phenol,

wherein the polycarbonate resin molding has a light transmittance of 0.1% or lower in a wavelength of not longer than 410 nm.

2 . The polycarbonate resin molding according to claim 1 , comprising:

at least one of (A) 0.01 to 30% by weight of the ultraviolet absorber and (B) 0.01 to 30% by weight of the fluorescent whitening agent;

(C) 0.01 to 30% by weight of the hindered amine; and

(D) 0.01 to 30% by weight of the hindered phenol, each based on the polycarbonate resin.

3 . The polycarbonate resin molding according to claim 1 , further comprising a protective layer as an outermost layer of the polycarbonate resin molding.

4 . The polycarbonate resin molding according to claim 3 ,

wherein the protective layer is an acrylic coat.

5 . An illuminator cover comprising a polycarbonate resin molding according to claim 1 .

6 . The illuminator cover according to claim 5 , which covers an HID (High Intensity Discharge) lamp.

7 . The illuminator cover according to claim 5 , which covers an illuminator for a vehicle.

8 . An illuminator lens comprising a polycarbonate resin molding according to claim 1 .

9 . The illuminator lens according to claim 8 , which covers an illuminator for a vehicle.

10 . The polycarbonate resin molding according to claim 1 ,

wherein the fluorescent whitening agent is represented by formula (I):

wherein R 1 and R 4 each independently represents a hydrogen atom, an alkyl group or an alkoxy group;

R 2 and R 3 each independently represents an alkyl group; and

[A] represents a substituted aryl group or a substituted ethenyl group.

11 . The polycarbonate resin molding according to claim 10 ,

wherein the fluorescent whitening agent is represented by formula (II):

wherein R 5 to R 8 each independently represents an alkyl group; and

n represents an integer of 1 or 2.

12 . A method for producing a polycarbonate resin molding, comprising:

extrusion molding a polycarbonate resin composition, so as to form an extruded polycarbonate resin composition; and

blow molding the extruded polycarbonate resin composition,

wherein the polycarbonate resin composition comprises: at least one of an ultraviolet absorber and a fluorescent whitening agent; a hindered amine; and a hindered phenol.

13 . A method for producing a polycarbonate resin molding, comprising injection molding a polycarbonate resin composition,

wherein the polycarbonate resin composition comprises: at least one of an ultraviolet absorber and a fluorescent whitening agent; a hindered amine; and a hindered phenol.
