Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative sheet and a method for producing the same. This paper relates to notebooks and their manufacturing methods.

Decorative sheets in the Song Dynasty were made by processing paper, textile fabric, non-woven fabric, metal foil, plastic film, synthetic leather, human-made leather, etc., through printing, embossing, 1L pasting, etc. There's C. These decorative sheets are selected based on their performance depending on the application, but in particular,
When applied to violet products such as rate, electricity and -5dR products, strict performance is required, especially regarding strength such as surface scratch resistance, heat resistance, cold resistance, and weather resistance. It must have excellent processability and be suitable for production.

In particular, plastics are increasingly being used in minute hands as decorative materials for automobiles, electrical appliances, etc. mentioned above, so injection molding and reaction molding (l(IM)) are used. A hair clip is a makeup notebook that has processability suitable for application to processing methods such as vacuum forming and vacuum-pressure forming.
There are 1.

Currently, decorative sheets with processability as described above are produced by coloring or printing on films or sheets of polyvinyl chloride, ABC, polysterene, acrylic, etc., and providing a protective resin layer of ordinary thermoplastic resin Il & 1 as necessary. Either by using a decorative sheet made of plastic, or by using a vacuum forming method in combination, or by pre-forming the decorative sheet, placing it in a mold, and then injecting from the surface of the decorative sheet to integrate it. The method is adopted to

However, while the above-mentioned conventional decorative sheets have poor processability such as molding, they lack performance such as heat resistance, cold resistance, weather resistance, and surface scratch resistance. .

The present inventors have been involved in the production of decorative sheets for some time, and have attempted to improve the drawbacks of such conventional decorative sheets.
When used as a protective layer, the heat resistance and cold resistance are reduced without impairing the moldability of conventional decorative sheets.Moreover, by irradiating the polyarylate resin side with ultraviolet rays, some percentage of the resin can be removed.
: Outer thread # caused by O-oxyketone structure
The present invention was completed based on the discovery that weather resistance, especially kneading properties, can be improved by M hypercompatibility.

4j The first aspect of the present invention is a base material, a printing material, and a boria relay at least partially having a θ-oxyketone structure.
The second method is to form a printed layer on the base material using a conventional ink, and then apply it to the printed All 1 layer to form a polyarylate resin layer. The present invention also relates to a method for producing a decorative sheet, which is characterized in that the polyarylate resin layer is then irradiated with ultraviolet rays.

14 The present invention will be explained in detail below.

+ As the base material in the invention, paper, gold W4 foil or metal plate, plastic film or Shikuha sheet, wood base material, etc. can be used, and examples of paper include Masou paper, bleached kraft paper, titanium paper, art paper. , coated paper, six-layer board paper, paperboard, etc. Metal foils or gold foil plates made of iron, aluminum, copper, tin, gold, silver, etc. or alloys thereof; plastic films or sheets include polyethylene. film, polypropylene film,
Polyvinyl chloride film, polyvinylidene chloride, film, polyvinyl alcohol film, polycarbonate film, nylon film, polystyrene film, ethylene acetate-fused vinyl copolymer film, ethylene vinyl alcohol copolymer film, ionomer, etc. films or sheets As the wood base material, precious wood, etc. (processed so-called veneer, or composites thereof, etc. can be used. In addition, woven fabrics, non-woven fabrics,
Cured leather, natural leather, etc. can also be used, and should be appropriately translated and used in consideration of appearance, performance, and workability 1, depending on the material used.

Next, a printing layer can be provided on the base material as described above by printing using ordinary ink, and an appropriate vehicle is used as the ink, and in addition to the vehicle, pigments or A product made by kneading four dyeing dyes, a plasticizer, a stabilizer, a dividing agent, a solvent, a four-color selective agent, etc., is used as a vehicle, and IJ, ethylcellulose, and ethylhydroquinone are used as a vehicle.
Cellulose conductors such as I-hirulose, cellulose acetate brevi-quaternate, and cenlerose acetate.

A combination of chlorinated vinyl resin, Bossester resin, polyurethane resin, butycool resin, and other resins are used, and gravure printing is used as a saw type that prints with the above inks. method, off-line gravure stamp @ method, offset printing method, silk screen printing method, letterpress stamp @ method, seiden stamp 4Illri. ,
A known printing method such as a jet printing method may be used.

After a printed layer is provided on the ElIC-sheeted base material as described above, a poly-1-rylate resin shaft is provided on the printed noodle ball.

It is preferable to carry out the extrusion at a temperature of C to 250℃, and to extrude the layer at the same time as extrusion.Also, the thickness of Boaryaryl 11 fatty noodles is preferably 50cm to 100IJ4).The first colorant is used as the polyarylate resin. Alternatively, a layer of primer may be provided before printing the polyarylate resin layer.Next, the polyarylate resin layer formed as described above may be applied.

By irradiating ultraviolet rays in the manner described above, the boa arylate resin layer is given ultraviolet ray transmission properties. A certain external radiation shielding property is caused by ultraviolet rays (by 11t, some ester groups of the polyarylate resin constituting the polyarylate resin layer play a free υ role.
Although the polyarylate resin layer exhibits a deep color due to the Kinketone structure, it can actually be used in cosmetic sorting of amber colors other than white.

Incidentally, the following boa arylate resin layer may be subjected to a known embossing process.

The present invention has the above-mentioned 4A n-, and since the polyacrylate resin noodles are placed on the surface of the sheet, the moldability of the base material is impaired. ``Sukranoso-resistant'' Hirono, ), tri

This would prevent the printing layer and the base material from deteriorating due to ultraviolet rays, and the second invention with the water amount of 1111 would be able to easily produce the decorative sheet of the first invention.
