Embodiment 1

[0051] The base material is all wood pulp base paper (60% hardwood pulp, 40% softwood pulp), basis weight 65g / m 2 , 16% ash, Cobb 30s 21g / m 2 , front smoothness 82s.

[0052] The film material is a polyester film with a thickness of 35 μm for transfer.

[0053] The composition of the pre-coating is as follows: 68% of calcined kaolin, 15% of hollow balls, 14% of styrene-butadiene latex, 0.5% of sodium polyacrylate, 0.2% of carboxymethyl cellulose and 2.3% of calcium stearate. The solid content of the pre-coating is 46%, and it is coated by a doctor blade, and the coating amount is 7.2g / m 2 .

[0054] The composition of the top coating is as follows: calcined kaolin 10%, light calcium carbonate 18%, polyvinyl alcohol 10%, carboxylated styrene-butadiene latex 6%, 4-hydroxy-4'-isopropoxydi Phenylsulfone 24%, 2-anilino-3-methyl-6-dibutylaminofluoran or 2-(2-4-xylanilino)-3-methyl-6-diethylaminofluoran 10% , benzyl-2-naphthyl ether 17.8%, zinc stearate 4%, antioxidant 11000.2%...

Embodiment 2

[0059] Method is the same as embodiment 1, just change top coat coating amount and be 1.4g / m 2 , thus obtaining a thermosensitive recording material.

Embodiment 3

[0061] The method is the same as in Example 1, except that the lubricant in the top coating formula is changed to zinc stearate accounting for 6%, and paraffin wax emulsion accounting for 2%, thus obtaining a heat-sensitive recording material.

Abstract

The invention relates to a thermo-sensitive recording material, in particular relates to a multi-proof thermo-sensitive recording material, and discloses a high-gloss multi-proof thermo-sensitive recording material and a preparation method thereof. A precoating layer, a thermo-sensitive top coat and a pre-coating protective layer sequentially coat the front surface of a base material; and a back coating coats the back surface of the base material. The top coating technology comprises the following steps: compounding a film material coated with a top paint and the base material coated with a thermo-sensitive paint; and drying and then stripping, so as to obtain the high-gloss multi-proof thermo-sensitive paper, wherein calendaring is not needed. The high-gloss multi-proof thermo-sensitive recording material is excellent in performance, and lower in cost in comparison with the high-gloss thermo-sensitive paper which is obtained by ultraviolet (UV) top coating and solidifying.

Description

technical field [0001] The invention relates to thermosensitive recording materials, in particular to a multi-proof thermosensitive recording material. On the other hand, the present invention also relates to a method for making a multi-resistance heat-sensitive recording material. Background technique [0002] With the expansion of the application field of thermal paper, the special thermal paper market is also born. Such as single-proof, two-proof, multi-proof thermal paper, according to its protective properties, it has been widely used in lottery tickets, entertainment tickets, invoices, train tickets and other papers, as well as self-adhesive label paper such as supermarket label paper and logistics label paper. At present, the single-proof and three-proof thermal papers on the market need to be calendered to obtain high-quality appearance and high printing clarity, but the loss of thickness and stiffness is relatively large, which is not conducive to label paper die-c...
