Definitions
- the present invention relates to a hard coating composition for a decor sheet for decoration and protection of skin complexes and a decor sheet manufactured therefrom. More specifically, it is possible to realize both a glossy surface and a matte surface through one coating solution, and a matting agent and / Or, it relates to a hard coating composition for a decor sheet that does not generate glossy points even without using particles and thus has excellent appearance uniformity of the product, and a decor sheet manufactured therefrom.
- decorative sheets for decoration are widely used to decorate and protect the surfaces of products such as home appliances, electronic products, architecture, furniture, automobiles, etc.
- These decor sheets are divided into glossy and matte sheets depending on the shape of the surface.
- realizing a glossy surface in a decor sheet can be achieved through a material composition that excludes particles or phase separation substances that can cause light scattering after curing of the coating composition, while realizing a matte surface can be achieved by curing the coating composition. Since light scattering must occur on the surface, particles or additives that can increase surface roughness must be included in the material composition. Therefore, it is difficult to provide a decor sheet that can simultaneously realize a glossy surface and a matte surface through one coating composition composition. It was a difficult task even in our industry.
- a coating composition that can realize both a glossy surface and a matte surface through one coating composition composition is very necessary in terms of productivity because it can produce a decor sheet by freely selecting the glossy surface and the matte surface after coating, but its implementation is difficult. It was a very difficult situation.
- a technology that forms a microfolding pattern on the surface of the coating composition using a 172nm excimer has recently been widely used.
- the 172nm excimer hardens only about 1 micron of the surface of the coating composition, and the lower uncured coating composition is applied to the upper surface. It is absorbed into the surface of the hardened coating and takes advantage of the phenomenon of wrinkles forming on the surface. Therefore, when using this technology, there is no need to use additives such as particles to induce light scattering.
- a glossy point refers to a unique pattern that occurs intermittently in a shape that extends around a point when irradiating a 172nm Excimer on the surface of the coating composition. This creates a difference in gloss from the surrounding micro-folding pattern, making it difficult to evaluate the appearance of the product. It acts as a defect that reduces the uniformity of appearance. For this reason, it was inevitable to minimize the visibility of glossy points by using matting agents and particles in coating curing technology using 172nm Excimer, and it was not easy to implement a coating composition that could realize both glossy and matte surfaces. .
- the present invention was created to solve the above problems and meet the conventional requirements.
- the purpose of the present invention is a deco sheet that can realize both a glossy surface and a matte surface through a single coating solution and has excellent product appearance uniformity.

- 2-Hydroxyethyl acrylate (2-HEA) 4-Hydroxybutyl Acrylate (4-HBA)
- 2-hydroxypropylacrylate (2-HPA) 2-hydroxypropyl methacrylate
- 2-HEMA 2-hydroxyethyl methacrylate
- HPMA hydroxypropyl methacrylate

- the content of monofunctional acrylate monomer in the entire hard coating composition is 10 to 20% by weight, preferably about 18% by weight. If the content of monofunctional acrylate monomer is less than 5% by weight, it is difficult to control the viscosity of the hard coating composition. There is a risk that the adhesion between the substrate and the hard coating layer may be insufficient, and if it exceeds 30% by weight, the content of bifunctional or higher acrylate monomer may decrease, resulting in lowered reactivity.
- Bifunctional acrylate monomers used in the hard coating composition for decor sheets according to an embodiment of the present invention include 1,6-hexanediol diacrylate (HDDA) and hydroxypivalic acid neopentyl glycol diacrylate (HPNDA). , it may be one or more monomers selected from the group consisting of dipropylene glycol diacrylate (DPGDA) and tripropylene glycol diacrylate (TPGDA).

- the content of the bifunctional acrylate monomer in the entire coating composition is 15 to 20% by weight, preferably about 18% by weight. If the content of the acrylic monomer having two functional groups is less than 15% by weight, it is difficult to control the viscosity of the coating composition. There is a risk that the viscosity may decrease or the reactivity may be weakened, and if it exceeds 20% by weight, it may become difficult to control the viscosity of the coating composition, and the reactivity may also increase excessively.
- the acrylic monomer described above refers not only to acrylate but also to methacrylate or derivatives in which a substituent is introduced to acrylate or methacrylate.

Because these hexafunctional urethane acrylate oligomers have excellent reactivity, they can increase the hardness of the hard coating layer, and their molecular weight is relatively large, so they are excellent in mechanical properties such as durability and pencil hardness after forming the hard coating layer.

However, if the weight average molecular weight is less than 800, the hard coating layer may be damaged. Conversely, if the weight average molecular weight exceeds 5,000, the hard coating layer may be damaged. There is a problem that the hardness of the coating layer becomes weak.
- the hexafunctional urethane acrylate oligomer may contain 12 to 25% by weight of the total hard coating composition. If it is less than 15% by weight, the coating layer may be damaged, and if it is more than 25% by weight, the hardness of the coating layer may be lowered. It can happen.

- the decor sheets containing the hard coating compositions for decor sheets according to Examples 1 to 6 of the present invention have a glossiness of the matte surface even though only one hard coating composition for decor sheets is used. It can be seen that the gloss of 60 degrees is less than 5%, the gloss of 85 degrees is less than 14%, and the gloss of 60 degrees on the glossy surface is more than 90%. Not only can both a glossy surface and a matte surface be realized through a single hard coating composition, but also a hard coating. Even if no matting agent and/or particles are used in the composition, it can be confirmed that the product has excellent appearance uniformity as no glossy point occurs.
- the decor sheets according to Comparative Examples 1 to 12 which are outside the configuration of the present invention, have glossy points on the matte surface, and the gloss of the glossy surface is less than 90% at Gloss 60 degrees.
- the gloss of the glossy surface is less than 90% at Gloss 60 degrees.
- Comparative Examples 1 and 9 even if a hexa-functional urethane acrylate oligomer and a tri-functional urethane acrylate oligomer were mixed to form a pattern satisfying a gloss of 60 degrees 5% or less and a gloss of 85 degrees 14% or less, the pattern surface If a glossy point occurs, a problem arises in which the product cannot be used.
- the deco sheet according to the present invention has excellent tactile feel and provides excellent user satisfaction
- the deco sheet containing it is useful in various fields such as home appliances, electronic products, architecture, furniture, automobiles, etc. to decorate and protect the surface of products. can be used
