A method of manufacturing a gravure printing paper includes: providing a substance having an effect of inhibiting a binding between pulp fibers; preparing a mixture of pulp fibers and fillers; and adding the substance to the mixture; making a gravure printing paper using the substance-added mixture.

Method of manufacturing gravure paper

A coated printing paper the product of whose basis weight, density, Young's modulus in the machine direction and breaking length in the machine direction is within the range of no less than 1.0&#xd7;10g&#xb7;N/mbut not greater than 4.0&#xd7;10g&#xb7;N/m, and which offers excellent pliability, superior print gloss in the image area regardless of lower white-paper gloss, minimal small-scale gloss variations in the image area, and excellent workability with the printing machinery, more particularly a matte coated paper, is provided.

Printing coated paper

Printing paper superior in a texture, a feel and ease in turning the page is provided by adjusting the product of the paper density, the breaking length of a paper-making direction and the Young's modulus of the paper-making direction of the paper made by a paper machine within the limits of no less than 2&#xd7;10and no more than 10&#xd7;10g&#xb7;N/mby using the following means independently or in appropriate combination: a means of lowering paper density by increasing the compounding ratios of low-density pulp and low-density filler, using bulking chemicals or reducing press pressure during paper-making process, a means of lowering the paper breaking length of a paper-making direction by improving the compounding ratios of filler, and a means of lowering the Young's modulus of the paper by using a softening agent.

Soft printing paper

A method for introducing a gene into a plant, which comprises introducing a gene into a plant cell using a vector containing an adventitious shoot redifferentiation gene as a selectable marker gene under the control of a light-inducible promoter, and a vector for introducing a gene into a plant, which comprises a desired gene, an adventitious shoot redifferentiation gene as a selectable marker gene under the control of a light-inducible promoter, and a removable DNA element, wherein the selectable marker gene is positioned such that it behaves integrally with the removable DNA element, and wherein the desired gene is positioned such that it does not behave integrally with the removable DNA element.
