Problems solved by technology

[0015] Although the printing process of decorative papers has been significantly improved, it leaves many disadvantages related to their production methods, and especially coating techniques
[0016] The first disadvantage associated with the doctor blade coating technique is the difficulty in applying to porous, brittle papers such as decor paper the excess coating applied before the doctor blade and the mechanical stress of pressure and tension during contact
This coating technique causes many cracks during production
A second disadvantage is that the actual coating technique by contact leads to partial penetration of the coating into the paper substrate and thus to a greatly reduced ability of the paper to absorb resin
[0017] The production of decorative papers for the production of high- or low-pressure laminates with higher coating weights and / or to preserve a high absorbency presents many difficulties, as revealed by the prior art

Embodiment 4

[0056] Embodiment 4: according to the present invention:

[0057] This same plain white decorative paper sold under the trade name Arjosave by the company Arjowiggins was produced on a Fourdrinier type paper machine. After drying, the paper has 80g / m 2 Grams per square meter, Gurley porosity of 20s, Bekk gloss of 20s and ash content of 38%.

[0058] The paper thus obtained is rolled up.

[0059] In the second step, the same 10g / m 2 Dry weight layer C2 coats this paper.

[0060] The paper thus coated was printed by inkjet printing on an Epson(R) 7600 printer.

[0061] The paper is then impregnated with a melamine-formaldehyde resin in an aqueous medium.

[0062] This paper is laminated according to usual operating conditions to produce low pressure laminates.

Embodiment 7

[0066] Embodiment 7: according to the present invention:

[0067] The same plain white decorative paper sold under the trade name Arjoprint by the company Arjowiggins was produced on a Fourdrinier type paper machine. After drying, the paper has 80g / m 2 Grams per square meter, Gurley porosity of 20s, Bekk gloss of 140s and ash content of 38%.

[0068] The paper thus obtained is rolled up.

[0069] In the second step, the same 10 g / m 2 Dry weight layer C2 coats this paper.

[0070] The paper thus coated was printed by inkjet printing on an Epson(R) 7600 printer.

[0071] The paper is then impregnated with a melamine-formaldehyde resin in an aqueous medium.

[0072] This paper is laminated according to usual operating conditions to produce low pressure laminates.

Abstract

The invention relates to a method of producing decorative paper which is coated with at least one ink-fixing layer, which is printable and which can be impregnated with a thermosetting resin, in order to produce a high- or low-pressure decorative laminate. The inventive method comprises the following steps consisting in: (a) producing a base sheet of decorative paper using paper-making means; and (b) coating at least one of the faces of the base paper sheet with said at least one ink-fixing layer, by means of curtain coating. The invention also relates to high- or low-pressure decorative laminates comprising such decorative paper.

Description

technical field [0001] The present invention relates to a process for the production of decorative papers which can be impregnated with thermosetting resins while having good printability, especially for inkjet printing, and good resin absorption properties. The invention also relates to decorative paper impregnated with a thermosetting resin. The invention finally relates to a laminated decorative panel or profile comprising a decorative paper impregnated with a thermosetting resin. Background technique [0002] Laminated decorative panels or profiles (also known as "laminates") have been used for many years in residential and commercial and industrial premises. Typical applications of this type of laminate are floor coverings, especially those imitating parquet, upholstery, table tops, chairs, etc. [0003] The two main types of decorative "laminates" are: those known as high pressure laminates and those known as low pressure laminates. [0004] Decorative laminates, kn...
