(Industrial Application Field) The present invention is a method for making a matte surface by applying it to the shiny surface of metal such as metal foil such as aluminum foil, stainless steel foil, or tin foil, or plastic film on which metal such as aluminum is vapor-deposited. It concerns matte paint. More specifically, it has the effect of reducing the luster of metal foils or metallized films that are often used in packaging materials, etc., and has the effect of reducing the gloss, and does not come into contact with high-temperature parts during processing, or is directly heat-processed. To provide a heat-resistant matte paint that can form a film that does not cause blocking or discoloration even when exposed to heat, and whose matte effect is not impaired by heat. (Prior art) Conventionally, packaging materials for pharmaceuticals, foods, etc. have been typically made of metal foils such as aluminum foil or aluminum-deposited polyester films due to their excellent barrier properties, workability, and beautiful metallic luster. Metal-deposited plastic films have been used in large quantities. (Problems to be solved by the invention) However, in recent years, regarding these packaging products,
In order to clarify the guarantee and liability for the contents, the composition of the contents, handling precautions, usage instructions, and the name of the manufacturing company are printed on a part of the outer surface of the package.
It has become mandatory to clearly state the name and location of the person in charge of production. Many of these items are generally printed in fine print within a limited and small area of the individual package, but in the case of metal foil or metalized plastic film, due to the reflection of the metallic glossy surface. The problem has arisen that it is difficult to read the information contained in the documents. As a result, there is a risk of misuse of medicines and foods, as well as problems such as increased fatigue in pharmacies and food-related industries that handle large quantities of these products, but this problem has not yet been completely resolved. This is the actual situation. (Means for Solving the Problems) The present inventor has made extensive research to solve the above-mentioned problems, and as a result, has arrived at the present invention. That is, a resin mixture of 30 to 70 parts of nitrocellulose resin, 20 to 55 parts of acrylic resin, 5 to 25 parts of butylated urea resin, and 3 to 20 parts of n-butyl etherified melamine resin is coated in solid weight ratio. The paint obtained by dispersing and mixing 2 to 15 parts of synthetic silica with an average particle size of 0.005 mm or less in a vehicle containing a forming agent as a main component has good adhesion to metal surfaces or metal-deposited surfaces, and does not impair transparency. It provides a good matte effect without any heat, and has heat resistance so that the matte effect does not decrease due to heat.It also has excellent surface hardness and can be coated at low temperatures for a short time with good abrasion resistance. They completed the present invention by discovering that it can be formed by heating. The paint of the present invention can form a coating film having desired mechanical, thermal, and optical properties only by mixing four specific types of resin in a predetermined amount range and dispersing a specific silica in a predetermined amount. This is what happens. As the nitrocellulose resin, which is one of the main components of the vehicle of the paint of the present invention, all types of nitrocellulose resins, such as the regular type called RS type and the alcohol-soluble SS type, are used. Ru. As the acrylic resin used in the present invention, all thermoplastic resins and thermosetting resins can be used, but in particular, acrylic resins such as carboxyl groups, hydroxyl groups, glycidyl groups, or alkyl etherified methylolamide groups, A thermosetting material having a functional group capable of reacting with the amino resin in its side chain is preferred. The butylated urea resin used in the present invention may have any degree of methylolation, any degree of alkyl etherification, or any degree of condensation. Furthermore, the n-butyl etherified melamine resin used in the present invention may have any degree of methylolation, any degree of alkyl etherification, and any degree of condensation. The matting agent used in the present invention is suitably silica, particularly synthetic silica, with an average particle size of 0.005 mm or less. (Function) In the present invention, the nitrocellulose resin mainly contributes to wear resistance and heat resistance, but when mixed with other resins, it also seems to have effects related to the generation of gloss. The acrylic resin gives flexibility to the coating film and contributes to its adhesion, and if it is thermosetting, it also provides crosslinking points and contributes to heat resistance and abrasion resistance. Butylated urea resin plays a fairly important role in the paint of the present invention, and n-
If only butyl etherified melamine resin is used, the coating film will not be sufficiently firm when drying is required in a very short period of time, such as the coating conditions in the field of application of the present invention. By blending in a suitable amount ratio, the excellent physical properties aimed at by the present invention can be exhibited. Synthetic silica, which is a matting agent, contributes to heat resistance and abrasion resistance in addition to the matting effect in the paint of the present invention. The average particle size of 0.005 mm or less is a necessary condition so that patterns such as letters on the base material are not hidden. (Effect of the invention) According to the present invention, in terms of solid content weight ratio, 30 to 70 parts of nitrocellulose resin, 20 to 55 parts of acrylic resin,
The main component is a resin mixture of 5 to 25 parts of butylated urea resin and 3 to 20 parts of n-butyl etherified melamine resin, and 2 to 15 parts of synthetic silica with an average particle size of 0.005 mm or less is dispersed and mixed in the main component. By applying the resulting paint to metal foil or metal-deposited plastic film used for packaging materials, etc., it can be made matte, making it easier to identify letters and characters printed on the base material. In addition, the coating film has good adhesion, hardness, good abrasion resistance, and excellent heat resistance, so even when exposed to high temperatures during molding, it does not show blocking properties or reduce the matting effect. It does not cause gloss or shine. However, the blended amount of nitrocellulose resin is 30
If the amount is less than 70 parts, abrasion resistance will not be obtained, and if it exceeds 70 parts, the matting effect will be inhibited and the adhesion will tend to decrease, so there is a suitable blending amount. If the amount of acrylic resin is less than 20 parts, the adhesion will be significantly reduced and the matting effect will also be slightly reduced. Moreover, if the amount exceeds 55 parts, the matting effect will be considerably impaired, and at the same time, the heat resistance will decrease, resulting in the disadvantage that gloss will appear on the matte surface during the heat processing process. When the amount of butylated urea resin is less than 5 parts, the abrasion resistance decreases and the matting effect also decreases a little. If it exceeds 25 parts, the adhesion and matte effect will be significantly deteriorated. For n-butyl etherified melamine resins, if the amount is less than 3 parts, the matting effect will be significantly reduced, and if it exceeds 20 parts, the matting effect will be significantly impaired, and at the same time, the adhesion and heat resistance will also be reduced. As matting agents, organic resin powders such as thermoplastic resin powders such as polyethylene, polyamide resins, and fluorine resins, thermosetting resin powders such as melamine resins, guanamine resins, and crosslinked polystyrene resins, as well as silica, alumina, and magnesium carbonate are used. There are powders of various inorganic compounds such as calcium carbonate, barium sulfate, etc., but organic resin powders have excellent matting effects and transparency, but have a common drawback of poor heat resistance. In the case of inorganic compound powder, there is no problem in terms of heat resistance, but although it has a matting effect, it has disadvantages such as making the coating opaque and being too hygroscopic to withstand use. Synthetic silica Only the powder exhibits the desired performance. However, powders other than silica may also be used in combination with the synthetic silica powder in an amount that does not impair coating performance, in the hope that they will have an effect as a lubricant on the coating surface. Naturally, if the amount of synthetic silica is less than 2 parts, no matting effect will be obtained at all, but the adhesion and heat resistance will further deteriorate. Also, 15
If the amount exceeds Hereinafter, the effects of the present invention will be explained in more detail with reference to Examples, but it goes without saying that the invention is not limited in any way to the extent that it does not significantly depart from the spirit of the present invention. .

Example 7 In Example 6, the amounts of butyl etherified melamine resin and synthetic silica were increased to 9.18 parts and 9.18 parts, respectively.
This is the case when the amount is increased to 3.42 parts. Comparative Example 7 In Example 1, N/C resin varnish was 50.00
part, 37.50 parts of acrylic resin, 15.00 parts of butylated urea resin, 8.50 parts of synthetic silica, and 1.00 parts of butyl etherified melamine resin, and when the amount of butyl etherified melamine resin is below the lower limit of the specified blending range. This is an example. Comparative Example 8 This is a case where the amount of butyl etherified melamine resin in Comparative Example 7 was 45.00 parts, exceeding the upper limit of the predetermined range. Comparative Example 9 N/C resin varnish in Example 1 was 50.00
parts, 37.50 parts of acrylic resin, 15.00 parts of butylated urea resin, butyl etherified melamine resin.
This is a case where the amount of synthetic silica is 0.70 parts, which is outside the lower limit of the predetermined range. Comparative Example 10 This is an example in which the amount of synthetic silica used in Comparative Example 9 exceeds the upper limit of the predetermined range. Comparative Example 11 In Example 1, synthetic silica was slightly added to 3.24 parts.
At the same time, polyethylene powder, which is an organic matting agent, was significantly increased to 2.40 parts. Comparative Example 12 Comparative Example 11 was further improved by adding 3.53 parts of synthetic silica and 4.80 parts of polyethylene powder. Comparative Example 13 Magnesium carbonate (manufactured by Asahi Glass Co., Ltd.; AM-90) was used as a representative inorganic matting agent other than silica, and the synthetic silica in Example 4 was replaced with the same amount of magnesium carbonate, 3.24 parts. It is something that Example 8 The heat-resistant matte paints obtained in Examples 1 to 7 and Comparative Examples 1 to 13 were coated on a 20 micron thick single-glazed hard aluminum foil to a dry coating thickness of 2 microns. The sample was applied to a glossy surface and immediately heated and dried at 180°C for 10 seconds, and then subjected to an adhesion test, a heat resistance test*, an abrasion resistance test, and a matte degree test. Shown in the table. The evaluation is on a five-point scale, with 1 being bad and 5 being good. *The heat resistance test method uses a sample of 22 cm vertically and 7.5 cm horizontally.
Align the glossy surface of a 20 micron thick single-glazed hard aluminum foil with the coated surface cut into cm pieces, and use a heat sealer equipped with a heat seal bar measuring 2 cm in height and 6 cm in width to seal 5.5 kg/cm 2 . After applying pressure for 3 seconds at a predetermined temperature, the laminated foil is peeled off, and the degree of contamination on the peeled surface is determined.

[Table] Example 9 As an example of the use of the present invention, hard aluminum foil,
Both sides of a 20 micron thick single gloss rolled product were printed with a printing ink containing nitrocellulose as the main component of the vehicle.
The matte paints of Steps 7 and 7 were applied to a dry film thickness of 1.5 microns and dried in a drying oven at 180°C for 10 seconds to form a matte paint layer, and the matte side was coated with vinyl chloride acetic acid. A heat-sealing adhesive whose main component is vinyl copolymer resin is applied to a dry film thickness of 3.5 microns, and dried in a drying oven at 180°C for 10 seconds to form a heat-sealing adhesive layer. We produced aluminum foil for PTP used for packaging. Blister packaging was performed by heat seal packaging using the above-mentioned aluminum foil for PTP and vinyl chloride sheet. The surface coated with the matte paint of the blister packaging exhibits a matte state similar to that of the matte side, and the characters printed on both sides are clear without reflection or dazzle. It was decipherable.
