Problems solved by technology

[0005] However, a conventional method includes a separate process of subbing treatment or printing for the purpose of improving the adhesion between PET and metal deposition layers, thus reducing the processing efficiency
[0006] In addition, because the fine lines are formed on one surface of the PET, and then the underlying treatment or printing is performed on it, the fine line effect on the PET surface is reduced

Embodiment 1

[0119] at 10 -4 Aluminum was vacuum-deposited at 1400° C. on a generally untreated PET film with a thickness of 30 μm as the base layer, thereby forming a layer with a thickness of layer of metal treatment. Then, the binder resin composition was applied to a 100 μm thick soft PV film (including 25 wt % of a plasticizer) as a coating film layer, thereby forming a 10 μm thick binder resin layer. Subsequently, the base layer formed of the metal-treated layer and the binder resin layer was dry-laminated, thereby manufacturing a decorative film.

[0120] One binder resin is an ester resin (solution with a solid content of 30 wt%), which includes NPG, EG, isophthalic acid, and terephthalic acid. The curing agent was of the TDI adduct type (solution with NCO content 7 wt%). The coupling agent was epoxysilane compound KBM403 (Shin-Etsu Chemical Co., Ltd.). The accelerator is an aziridine compound shown in Formula 4.

[0121] The composition of the components is listed in Table 1...

Embodiment 2

[0125] A decorative film was produced in the same manner as in Example 1 except that a glycidylamine compound represented by Formula 10 was used as an accelerator.

Embodiment 3

[0127] A decorative film was manufactured in the same manner as in Example 1 except that SL10 (a co-extruded sheet of PET and polyester resin having a thickness of 30 μm) manufactured by SKC Inc. was used as the base layer.

Abstract

The present invention relates to an adhesive resin composition for a decorative film, and to a decorative film including same. In the present invention, an amine-based (including N) accelerator having a functional group which can react with active hydrogen is used for increasing the reaction rate of an adhesive resin which is required for the preparation of a decorative film having a metallic effect, thereby ensuring coating stability and increasing the reaction rate. Thus, according to the present invention, an adhesive resin which has little deviation in quality (boil resistance) between and within rolls can be provided in a short time.

Description

technical field [0001] The present invention relates to an adhesive resin composition for a decorative film and a decorative film using the same, and more particularly, to an adhesive resin composition for a decorative film which includes an amine accelerator to secure a coating Stability and increased reaction rate, so that the decorative film has little quality deviation (boiling resistance) between and within rolls in a short time, and the decorative film produced using it. Background technique [0002] High-gloss metal sheet or film is a decorative material that has a superior metallic luster equivalent to metal plate or sheet, which is used in a variety of applications such as building materials, household appliances, automobiles, business cards and Label. [0003] Korean Patent Publication No. 2006-78530A discloses a high-gloss sheet stacked on an iron plate or an aluminum plate, which exhibits a metallic texture, and is used as a high-gloss decorative material. The ...
