Problems solved by technology

[0007] However, the disadvantage of metal deposition technology is that the construction cost of the equipment infrastructure is high, and the deposition cost increases sharply when the size of the deposition object increases
In addition, metal deposition technology requires a long manufacturing time due to more than three separate processes, making it difficult to achieve mass production
In addition, the problems of the deposited film are that the deposited film is easy to break due to its inflexibility, the adhesion between the substrate surface / deposited surface / transparent surface is poor, and the realized colors are limited, so the deposited film exhibits poor performance. Satisfactory film properties
[0008] In addition, the disadvantages of metal coating technology are that the total reflection performance of the coating film is low and the appearance is not as good as that of the deposited film, and the workability of the technology is poor, making it difficult to paint a wide part

Embodiment

[0050] The coating composition was prepared according to the composition shown in Table 1. The prepared coating composition sample was sprayed onto the substrate (material: PET / polyurethane substrate), then dried to form a coating film, and the following physical properties of the formed coating film were measured. The measurement results of physical properties are shown in Table 1.

[0051] Adhesion to the substrate

[0052] The adhesion to the substrate was measured by the cross cut (ASTM, ISO standard) method.

[0053] Adhesion between layers

[0054] The adhesion between the layers was measured by the cross cut (ASTM, ISO standard) method.

[0055] Gloss

[0056] The gloss is measured by a gloss meter.

[0057] Brightness (reflectivity)

[0058] The brightness is measured by the CM-2500 meter.

[0059] Black brightness

[0060] The black brightness is measured by the CM-2500 meter.

[0061] Film drying speed (relative value)

[0062] After the coating film is formed on the OHP fil...

Abstract

The present invention relates to a paint composition and a reflective plate for a screen, comprising a coating layer of the same and, more specifically, to a paint composition, which is capable of enabling spray coating to increase the work process rate, allowing mass production and low-price production of coating articles, being applied to large-sized articles, showing a high reflectance comparedwith the level of deposition, realizing a relatively high contrast ratio compared with the deposition, and attaining a coating film with excellent flexibility and adhesiveness, and to a reflective plate for a screen, comprising a coating layer of the same.

Description

[0001] Cross references to related applications [0002] This application claims the priority of Korean Patent Application No. 2015-0069967 filed at the Korean Intellectual Property Office on May 19, 2015, the entire content of which is incorporated herein by reference. Technical field [0003] This application relates to a coating composition, and more specifically, to a reflective plate or reflective layer applied to a screen. Background technique [0004] Optical devices such as a projector or an image projector include a screen for displaying an image, and a main body that emits light by using a lens or the like to display the image on the screen. The screen has a light reflection layer on a light incident surface, thereby displaying an image by reflecting light passing through a lens or the like. [0005] The light reflection performance of the light reflection layer was evaluated based on the total reflectance of light. That is, when 100% of incident light is INPUT, the amount...
