Abstract

PURPOSE:To obtain titled composition having metallic gloss stable with time even after application, with stable dispersion and low cost, suitable as decorative coating, by dispersing in the aerosol liquid chief agent a lamella material consisting of laminated resin film chips with the maximum width smaller than a specific value. CONSTITUTION:The objective composition can be obtained by dispersing in the aerosol liquid chief agent a lamella material consisting of laminated resin film chips with the maximum width <=100mu (e.g., of laminated polyester film, with a thickness of 18mu and the maximum width of 35mu). The container for the above composition is pref. of a type provided with, e.g., straight shank valve free from neck portion. EFFECT: Change of the laminated resin film constitution would provide aerosol compositions of metallic gloss with various color tones.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to aerosol compositions, particularly aerosol compositions having a metallic luster.

In general, paints, especially decorative paints for outdoor and indoor equipment such as glass, toys, and ornaments, and paints that exhibit a variety of colors and glosses depending on one's taste are required. Those with metallic luster are no exception.

Conventionally, laminated materials consisting of fine aluminum metal powder or minute pieces of foil have been used as materials to obtain metallic luster, but such metallic laminated materials are easily corroded and lose their luster over time. The deterioration is significant, and if it comes into contact with the human body, it may irritate the skin and cause 9 rash. In addition, there are restrictions on the dispersion medium in which the lame material is dispersed, and the high specific gravity makes it difficult to maintain a stable dispersion state. However, depending on the type of metal, it is very expensive.

The present invention has been made based on the above-mentioned circumstances, and its objects are to have a stable metallic luster over time even after application, to have a stable dispersion state, and to be inexpensive and other than other materials. The object of the present invention is to provide an aerosol composition that does not cause any problems.

A feature of the present invention is that it contains a laminated material consisting of minute pieces of laminated resin film having a maximum width of 100 μm or less.

The present invention will be specifically explained below.

In the present invention, one example is a laminate of unsaturated polyester films, and the other is cutting a laminate resin film that has a high reflectance of light of a specific or non-specific wavelength and has a metallic luster. is 18μ.

The maximum width of one piece is 100 μm or less, for example, 40 μm, and this is used as a lamella to prepare an aerosol composition. Specifically, the lame material is dispersed in the liquid main ingredient of the aerosol.

The aerosol composition of the present invention is as described above, and since its laminated material is composed of minute pieces of laminated resin film, it is inexpensive and has no risk of being corroded by the aerosol's main ingredient or additives. It must be extremely stable over time, and when used, it will exhibit a stable metallic luster for a long period of time. In addition, the glitter material can be easily obtained with a desired specific gravity, including those with a small specific gravity, and therefore it is easy to match the specific gravity with the main ingredient of the aerosol in which it is dispersed. Therefore, the dispersion state of the lame material can be made extremely stable, resulting in a stable aerosol product.

Furthermore, since the lame material used in the present invention has a maximum width of 100μ or less, even when it is filled into an aerosol container and used, it is unlikely to cause clogging at the injection port, pulp portion, etc. of the aerosol container. , high reliability is obtained.

Also, what is the metallic luster that the laminated resin film has?

It is determined by the structure of the film laminate (material and thickness of each layer, etc.), and by changing this, it is possible to change the wavelength at which the reflectance is particularly high.

By obtaining and using lame materials with metallic luster in various tones, aerosol compositions with metallic luster can be obtained.

As a container for storing the aerosol composition of the present invention, it is preferable to use a container comprising straight shank pulp having no neck portion.

As described above, the present invention provides an aerosol composition that has a stable metallic luster over time even after application, has a stable dispersion state, is inexpensive, and does not clog an aerosol container. can do.
