But there is not yet friction variable color in the prior art or roll look cheque paper of wiping.
Content of the invention
It is an object of the invention to provide a kind of friction variable color or roll look cheque paper and preparation method thereof of wiping.
The antifalse effect of paper of the present invention is good and prepares simple, conveniently.
The invention provides a kind of friction variable color or roll look cheque paper of wiping, it is by paper technology
To comprise to rub variable color or roll and draw the sizing composition of off-color material or coating composition at paper
Surface and obtain, wherein said friction variable color or roll draw an off-color material account for described sizing composition or painting
0.01-30 weight % of feed composition weight.
The friction variable color of the present invention or roll look cheque paper of wiping, is different from fluorescent anti-forge paper, temperature-sensitive false proof
Paper, fluorescent fiber cheque paper etc., the light fastness of this cheque paper is fine, friction variable color or roll look of wiping
Material manufacture paper with pulp into paper after the term of validity more than 20 years and preparation method is simple.
Detailed description of the invention
The friction variable color of the present invention or roll look cheque paper of wiping, its outward appearance can be the anti-of colorless or colored
Pseudo-paper, the so-called colourless appearance color referring to cheque paper detects by an unaided eye and is hardly visible color；So-called
Coloured appearance color referring to cheque paper detects by an unaided eye and can clearly recognize color.Through friction of exerting oneself
Or after rolling and drawing, with the naked eye clearly recognizable can there are other colors different from paper color in paper surface,
For example red.
The friction variable color of the present invention or roll look cheque paper of wiping and become by friction will be comprised in paper technology
Look or roll and draw the sizing composition of off-color material or coating composition obtains at paper surface,
Wherein said friction variable color or roll draw an off-color material account for described sizing composition or coating composition weight
0.01-30 weight %.Described sizing composition or the painting comprising friction variable color or rolling stroke off-color material
Material that feed composition uses except normal (as calcium carbonate, kaolin, water soluble starch, adhesive,
Auxiliary agent, water etc.) outward, possibly together with 0.01-30 weight % friction variable color or roll draw an off-color material.And
After with the addition of friction variable color or roll stroke off-color material in sizing composition or coating composition, friction
Variable color or roll draw an off-color material do not change the sizing composition in known papermaking process or coating group
The function of compound, is only to the sizing composition in known papermaking process or coating composition
Increase a friction variable color or roll a stroke colour change function.
According to one embodiment of the invention, described friction variable color or roll look cheque paper of wiping and used
Friction variable color or roll draw an off-color material be non-chemical stain microcapsules.Described microcapsules light fastness exists
More than 3 grades (International Wool sun-proof classification standards).Described microcapsules are with the hot polymerization producing microcapsules
Resin (such as melamine formaldehyde resin) is by the colored pigment being dissolved in high boiling solvent or dyestuff (state
Pigment more than 3 grades for the border wool sun-proof classification standard or dyestuff, such as oil red) it is rolled into microcapsules.
The appearance color of microcapsules is shallow as far as possible, and the particle size of microcapsules can not affect the skill of paper technology
Art requires.
According to one embodiment of the invention, friction variable color or roll draw an off-color material be series pigments or
Based dye etc..
Described friction variable color or roll look cheque paper of wiping, nondiscolouring (this under having the pressurization of bigger gravity
Point is different from chemical stain).Even above-mentioned hot polymerizable resin (such as melamine formaldehyde resin)
By the colored pigment being dissolved in high boiling solvent or dyestuff (International Wool sun-proof classification standard 3 grades with
On pigment or dyestuff) microcapsules that are rolled into, cheque paper when presswork or during paper carrying or
When external force pushes, cheque paper surface, all without producing color change, has only and is used by harder smooth object
Color change is produced, as with the rubbed variable color of scratching of the edge of coin or roll and draw the present invention and prevent during power scratching
Pseudo-paper surface, paper surface is become the visibly different color with paper color by colourless or light colour,
Such as redness；Or paper surface is become redness etc. by green phase-black discoloration.Additionally due to the particle diameter of microcapsules is little
In paper sheet thickness, when cutting with cutting knife, cheque paper surface changes all without producing color.
Friction variable color in described papermaking process or roll wipe look sizing composition or Coating material composition
Thing, refers to the sizing composition in single gummed paper or wood-free paper or coating paper production process or Coating material composition
Thing.
In a preferred embodiment of the invention, described friction variable color or roll draw an off-color material account for institute
State 0.05-15 weight % of sizing composition or coating composition weight, preferably 0.1-10 weight %,
More preferably 0.2-5 weight %.
The present invention also provides a kind of method preparing cheque paper of the present invention, and it includes sizing composition
Or coating composition and friction variable color or roll and draw an off-color material and mix and grind；Ground comprising is rubbed
Wipe variable color or roll and draw the sizing composition of off-color material or coating composition at paper surface；So
After coated paper is dried to obtain described cheque paper.The inventive method is simple, can be with successful Application
