Description
Technical field
The present invention relates to have with pigment and adhesive on the two sides of body paper is the coated paper for printing of the coating layer of main component, more particularly, the present invention relates to that not only density is low, and blank sheet of paper gloss is than good coated paper for printing of printing applicability such as higher, print gloss or printing smooths.
Background technology
General coated paper for printing is that coating is that the coating fluid of main component is made with pigment and adhesive on body paper, can be divided into cast-coated paper, art paper, coated paper, little coated paper etc. according to the coating weight of coating fluid or the ornamenting method of coated paper.These coated papers are implemented polychrome printing or single color printing again, except commercial with the printed article use as handbill, brochure, advertisement poster etc., also extensively use as publications such as books, magazines.In recent years, printed article is at viewing and admiring of development, colorize, and outward appearances such as the whiteness of coated paper for printing or flatness are than more coming into one's own in the past.
When making coated paper, high more to the quality requirement of product coated paper, then increase the coating weight of coating fluid more, so cause the density of coated paper to increase.That is, the glossiness coated paper that blank sheet of paper gloss is high, its density is 1.15g/cm normally
3More than, and the coated paper density of the low dullish of blank sheet of paper glossiness 0.9g/cm normally
3～less than 1.15g/cm
3
In addition, the manufacturing cost of coated paper itself not only, and consider the lightweight of strong request coated paper for printing from seeking to reduce the viewpoint that coated paper is implemented the logistics costs such as printed publication of printing.The lightweight of coated paper can be by the coating weight of minimizing coating fluid or quantitatively realizing of reduction body paper.The former does not destroy printing qualities such as printing smooth or print gloss, and the reduction of latter Ze Yin paper thickness causes the presswork deterioration, or the third dimension of forfeiture brochure, also has the problem that causes feel to worsen.Therefore, even the coated paper that the sector expectation makes the coated paper lightweight also not decrease the bulky of paper thickness comes out.
The coated paper of dullish or do not carry out the coated paper that smoothing such as superpressure light is handled, general compare with the coated paper of reflecting feel that thickness is big, density is low, this is because the difference of smoothing treatment conditions such as superpressure light to a great extent, to guarantee highly that paper is thick and must not exclusively carry out smoothing and handle, also must make treatment conditions (particularly, press polish treatment temperature, pressure, processing hop count etc. being arranged) gentleness even perhaps carry out the smoothing processing.Yet, save smoothing and handle, even or do not save and when making treatment conditions gentle, surface smoothing reduction that might the goods coated paper, printing qualities such as printing smooth or print gloss worsen.
The thick so thin coated paper of paper as obtaining quantitatively low promptly, obtains one of method that the coated paper of bulky uses, and has proposed to adopt in the process of making coated paper the method (with reference to Patent Document 1～2) of hot soft calendaring.Yet, being provided with of the certain not only hot soft press-polishing machine of this method is indispensable, and, even adopt hot soft press-polishing machine, and when using general ground paper or coating fluid to form, also, obtain the coated paper of required bulky, must consider that employed ground paper or coating fluid form seldom to can the be satisfied with coated paper of bulky of quality.
In a kind of method, the method for cooperative mechanical wood pulp in body paper is arranged with the bulkyization of body paper own.Compare with chemical pulp, the common mechanical wood pulp produces effect to the bulkyization of body paper because fiber is hard.Yet, though groundwood pulp is according to the degree of its kind or making beating and difference, because general surface strength is low, so establish the coated paper that coating layer obtains on the many body paper of groundwood pulp use level, living easily problem such as peel off when having printing.In addition, this body paper not only flatness on surface is poor, and owing to easily exceedingly permeate coating fluid, so also exist difficulty to draw the problem of coating fluid performance fully.
As improving the method that obtains the coated paper printing quality by the body paper of cooperative mechanical wood pulp, the known big kaolinic method of bulky (with reference to Patent Document 3) of sedimentation volumn that in coating layer, cooperates, when adopting this method, the balance of the density of coated paper and blank sheet of paper gloss is insufficient, seldom arrives print gloss or the good coated paper of printing smooth.In addition, as improving by the cooperative mechanical wood pulp, in add the method that makes the printing quality of coated paper as the body paper of the amorphous silica of filler, known pigment to coating fluid is selected the method (with reference to Patent Document 4) of the pigment of use narrow particle size distribution, but make occasion in this way, since cooperate the filler that hinders fiber combining, the problem that exists surface strength to reduce, the difficult balance that obtains excellent printing applicability and density.
As the another kind of method that makes the body paper bulky, also know the method (with reference to Patent Document 5) that makes body paper contain bulk agents such as softener.Though yet above-mentioned bulk agent hinders wood pulp fibre combination each other, owing to be original effect, so the coated paper that is obtained by the body paper that cooperates this bulk agent, difficulty makes the suitable printing intensity of this coated paper maintenance.In addition, the body paper that contains bulk agent is the same with the occasion of the body paper of a large amount of cooperative mechanical wood pulps, and not only surface smoothing is poor, and owing to exceedingly easily permeate coating fluid, so insufficient shortcoming of drawing the coating fluid performance is arranged.
As improving the method that contains the coated paper printing quality of bulk agent in the body paper, proposed to cooperate the method (with reference to Patent Document 6) of plastic pigment, must in fact can not be suppressed at about 1.0g/cm to the density of coated paper relatively carrying out the processing of superpressure light under the exacting terms when adopting this method
3Below.
As the conventional art of the coated paper that obtains bulky, except above-mentioned, also proposed specific layering kaolin and be engaged in method (with reference to Patent Document 7～9) in the coating layer.Yet these motions are owing to all using the bigger layering kaolin of size ratio, so existence can only obtain the difficult point of the lower coated paper of blank sheet of paper gloss.
As previously discussed, even prior art can not make the low and blank sheet of paper gloss of density also than higher, and printing applicabilities such as print gloss or printing smooth might as well coated paper.
