In order to achieve the above object, the present invention provides a method for producing a liquid crystal composition comprising UREA, GLUCOSE, N, N-DIMETHYL ACRYLAMIDE POLYMER, CITRIC ACID, 50 parts by weight of a copolymer of SODIUM CITRATE and water, 49 parts by weight of ETHTHYL CELLOSOLVE, 0.85 part by weight of THICHENER and 0.15 part by weight of METHYLPAREBEN were prepared. And the mixed neutralized adsorption neutralizing coating agent (a) is coated on the film (p).

Further, the stirring is performed at 3000 RPM for 10 minutes to 15 minutes.

In addition, the adsorption neutralizing coating agent (a) is applied and sprayed on the film (p) and dried with the adsorption neutralizing coating layer (c).

In addition, the adsorption neutralizing coating agent (a) is characterized by being in a solution state.

The composition ratio of the copolymer was 17 parts by weight of UREA, 3 parts by weight of GLUCOSE and 1 part by weight of N, N-dimethylacrylamide polymer (N, N-dimethylacrylamide polymer) , 3.5 parts by weight of citric acid (CITRIC ACID), 3.5 parts by weight of sodium citrate (Sodium Citrate) and 72 parts by weight of water.

The present invention relates to a method for manufacturing a sheet-like product, which comprises the steps of mixing a copolymer, ethylcellosolve, a thickener, and methylparaben in a mixer to form a neutralized coating layer on a film with an adsorption neutralizing coating, The function of neutralizing and removing adsorbed formaldehyde and volatile organic compounds contained in paints and adhesives used in manufacturing can be improved in one dimension, and the use life of the adhesive can be long-term.
