Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a stereoscopic image display panel in which an arbitrary image pattern is formed at a predetermined position on a base material. Such a display panel can be used, for example, as an instrument panel for various devices, a display panel on which maps, landscape images, etc. are arranged, a dial for a vehicle speedometer, and the like.

[0002]

2. Description of the Related Art Conventionally, characters, numbers, etc. on a dial of a meter have generally been formed by printing on a resin base material, and are usually flat images in many cases. However, in recent years, in order to add texture to these display images and improve the visibility, in response to the increasing trend toward higher grades and the demand for diversification, three-dimensionalization of images has been studied.

As a method for making a display image three-dimensional,
For example, thick film printing may be used to give a three-dimensional effect, and hot stamping may be used to transfer irregularities. However, both have drawbacks in that the image forming method is complicated and mass productivity is poor. Further, for example, if the molding method is used, mass production is possible, but there is a problem that it cannot be applied to a fine pattern.

As a method of forming a three-dimensional image excellent in mass productivity and decorativeness, for example, in Japanese Patent Laid-Open No. 122220/1990, a photo-curable resin layer is formed on a substrate, and the photo-curable resin layer is formed in a predetermined pattern. There is disclosed a method of manufacturing a three-dimensional image display panel by forming an uneven pattern by exposing and curing the portion of (3) and developing and removing the uncured portion. However, if only the stereoscopic image layer is formed on the display board, the brightness of the stereoscopic image is low in dark light, and thus the stereoscopic effect is poor and the visibility is poor.

On the other hand, when it is used as a display board, it is necessary to withstand various stresses such as deformation when it is incorporated in equipment and vibration during operation of equipment. Especially the three-dimensional display board,
As the thickness increases, the stress against deformation increases,
A flexible image composition is required as compared to a two-dimensional image.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks, and an object thereof is a method of manufacturing a stereoscopic image display panel which is excellent in flexibility and visibility even in dark light. To provide.

[0006]

The method for producing a stereoscopic image display panel according to the present invention comprises forming a photopolymerizable resin layer on a substrate, exposing it through a mask and curing it, and removing the uncured portion to give a predetermined composition.

Since the addition-polymerizable monomer (c) has an OH group in the molecule, it enhances the developability of the unexposed portion when developing with a dilute aqueous alkaline solution after exposure, and also the fluorescent material described later. When dispersed, acts as a good dispersant.

When the amount of the addition-polymerizable monomer (c) in the photopolymerizable resin composition is small, the developing time is long and the dispersibility of the pigment is low, and when it is large, the dispersibility of the pigment is improved. Since the development resistance of the exposed portion decreases and cold flow of the photocurable resin layer itself easily occurs, it is limited to 5 to 100 parts by weight relative to 100 parts by weight of the linear copolymer (a), Preferably 20-70
Parts by weight.

When the amount of the photopolymerization initiator (d) in the photopolymerizable resin composition is small, the curing time becomes long, and

When the amount of the fluorescent material (e) in the photopolymerizable composition is small, the effect of fluorescence becomes small, and when it is large, the linear copolymer (a) and the photopolymerizable unsaturated compound (b) are contained. Since the compatibility is markedly reduced, the dispersibility is not improved even if the addition amount of the addition polymerizable monomer (c) is increased, aggregates are generated, and the pigment or dye precipitates in the solution.
