It is obtained by providing at least one side of bulky base paper with two layers of coated layers consisting essentially of pigment and an adhesive, and the pigment component of an undercoating layer uses specific fine grinding figuline in specialized range having d50<SUB>1</SUB> average particle diameter measured by a light scattering method and d50<SUB>2</SUB> average particle diameter measured by a settlement method.
Description
Technical field
The present invention relates to the coated paper for printing of the bulky that flatness obtains improveing.
Background technology
General coated paper for printing carries out drying with pigment and adhesive after as the coating liquid of principal component at least 1 coating of body paper and makes.Coated paper for printing is categorized into cast-coated paper, art paper, coated paper, little coated paper etc. according to the coating weight of coating liquid and the processing method of art paper.These art papers are implemented polychrome printing or single color printing thereon, are extensive use of with printed article or as publication such as books, magazine as advertisement, brochure, picture poster etc. are commercial.
In recent years, along with visual, the colorize progress of printed article, higher for the requirement of the high quality of coated paper for printing.Concrete is glossiness, smoothness and the whiteness that requirement improves coated paper for printing itself.
As one of method that improves the coated paper for printing smoothness, the someone proposes coating is cooperated the scheme (with reference to patent documentation 1～3) of fine grinding potter's clay.Fine grinding potter's clay (デ ラ ミ ネ one テ Star De カ オ リ Application (delaminated kaolin)) considers from giving the coating flatness that because shape of particle is flat or tabular it is preferred that its pigment composition as coating is used.
As one of additive method that improves the coated paper for printing smoothness, be to adopt the pigment composition (with reference to patent documentation 4～7) of satin white as coating.Satin white for example is the Chinese white by the acicular crystal of calcium hydroxide and reacting aluminum sulfate generation, and its formal name is called three sulfo group calcium aluminates.Satin white is the inorganic complex with following general formula (1) expression, and the known coating surface of satin white that cooperated presents excellent flatness.
3CaO·Al
2O
3·3CaSO
4·31～32H
2O (1)
In the former coated paper for printing,, one deck coating (below it is called down coating) is set again and exists at the downside that plays coating (below it being called coating) as printing ink receptive layer function.
For example, as one of pigment composition that descends coating, it is known cooperating the coated paper for printing (with reference to patent documentation 8～10) of potter's clay and cooperating the coated paper for printing (with reference to patent documentation 11) of satin white.Yet, use fine grinding potter's clay as coated paper for printing the unknown so far of coating color composition down.
When coating was set down, it was common that this laminar surface flatness exerts an influence to the flatness of the last coating (printing ink receptive layer) that is provided with on the following coating usually, bore the glossiness of this layer about the flatness of the last coating that printing ink accepts.Therefore, in order to obtain all excellent coated paper for printing of glossiness, smoothness and whiteness, not only to the last coating (=printing ink receptive layer) of art paper but also must work hard to the structure of descending coating.
In addition, to coated paper for printing, except that requiring good glossiness, smoothness and whiteness, in recent years, had feel of art paper (paper hardness) and apparent specific volume amass the tendency that (apparentspecific volume) is concerned about especially one by one.Particularly, require it to have the more tendency of bulky character recently to making the art paper of publication.
In order to make more bulkyization of coated paper for printing, the someone proposes directly to make the method (with reference to patent documentation 12～13) of the bulky of body paper own or the method (with reference to patent documentation 14～16) that the coating layer that is coated on the body paper is handled by the soft calender of heat etc. or use hollow plastic pigments as the method (with reference to patent documentation 17～18) that is engaged in the pigment in the coating layer etc. by adding bulk agent.
That is, relating to original motion of bulkyization, is when adopting than the body paper of bulky as the body paper of coated paper for printing, and the art paper that coating coating liquid on body paper is obtained carries out press polish when handling, and minimizing is applied to the extruding force on body paper or the coating as far as possible.Yet, the alleviating of extruding force when press polish is handled, the coating smoothing effect when comparing press polish with unallayed occasion and handling has the tendency that diminishes.
Therefore, for obtain flatness good, in more detail, good in order to obtain the coating flatness, and the art paper of bulky, carry out the last coating before press polish is handled under the temperate condition, maintenance flatness to a certain degree is important.
Even carrying out gentle press polish handles, make one of prior art of the good art paper of flatness, as mentioned above, consider that adopting crystal form is needle-like or tabular Chinese white (for example satin white or the fine grinding potter's clay) method as last coating color from the viewpoint of giving the coating flatness.Other a kind of method then is that the thickness of coating is increased, and uses coating and shelters and the concavo-convex method of last coating contact-making surface.
Yet because the unit are amount of stipulating on the art paper (level ground amount) (area dry weight (areal driedweight)) is definite, last coating layer thickness not only must increase in vain, and goes up the density increase that the coating layer thickness increase must make art paper.Therefore, when adopting the former method, be difficult to obtain the art paper of bulky.
Do not emphasize the common coated paper for printing of " bulky ", generally its bulk density (bulk density) is at 1.15～1.25g/cm
3Scope.Therefore, said in this specification " coated paper for printing of bulky " refers to bulk density at 1.10g/cm
3Or 1.10g/cm
3Below, typically at 1.05g/cm
3Or 1.05g/cm
3Following art paper.Also have, the mensuration of bulk density is undertaken by the regulation of ISO 534:1988.
