a cross-linker; a lubricant that is any one selected from a group consisting of silicone wax, polyolefin wax, and paraffin wax; and water; wherein the cross-linker is either a compound having a plurality of oxazoline groups or a compound having a plurality of terminal blocked isocyanate groups. ### Claim 2 (depends on 1) The pretreatment liquid according to claim 1, further comprising: a cationic compound, wherein the cationic compound is any one selected from the group consisting of polyvalent metal salts, cationic polymers, and cationic surfactants. ### Claim 3 (depends on 1) The pretreatment liquid according to claim 1, wherein the resin dispersion is any one selected from the group consisting of nonionic dispersions, cationic dispersions, and emulsifier-dispersible anionic dispersions. ### Claim 4 (depends on 1) The pretreatment liquid according to claim 1, wherein the cross-linker is any one selected from the group consisting of nonionic dispersions, cationic dispersions, and emulsifier-dispersible anionic dispersions. ### Claim 5 (depends on 1) The pretreatment liquid according to claim 1, wherein the lubricant is any one selected from the group consisting of nonionic dispersions, cationic dispersions, and emulsifier-dispersible anionic dispersions. ### Claim 6 (depends on 1) The pretreatment liquid according to claim 1, wherein the resin dispersion has a solid content of 10% or less by mass based on a total mass of the pretreatment liquid. ### Claim 7 (depends on 1) An ink set comprising: the treatment liquid according to claim 1; and an ink composition containing a pigment. ### Claim 8 (depends on 2) An ink set comprising: the treatment liquid according to claim 2; and an ink composition containing a pigment. ### Claim 9 (depends on 3) An ink set comprising: the treatment liquid according to claim 3; and an ink composition containing a pigment. ### Claim 10 (depends on 4) An ink set comprising: the treatment liquid according to claim 4; and an ink composition containing a pigment. ### Claim 11 (depends on 5) An ink set comprising: the treatment liquid according to claim 5; and an ink composition containing a pigment. ### Claim 12 (depends on 6) An ink set comprising: the treatment liquid according to claim 6; and an ink composition containing a pigment. ### Claim 13 (depends on 1) A recording method comprising: applying the pretreatment liquid according to claim 1 to a textile; and applying by an ink jet method an ink composition containing a pigment to a region of the textile to which the pretreatment liquid is applied. ### Claim 14 (depends on 2) A recording method comprising: applying the pretreatment liquid according to claim 2 to a textile; and applying by an ink jet method an ink composition containing a pigment to a region of the textile to which the pretreatment liquid is applied. ### Claim 15 (depends on 3) A recording method comprising: applying the pretreatment liquid according to claim 3 to a textile; and applying by an ink jet method an ink composition containing a pigment to a region of the textile to which the pretreatment liquid is applied. ### Claim 16 (depends on 4) A recording method comprising: applying the pretreatment liquid according to claim 4 to a textile; and applying by an ink jet method an ink composition containing a pigment to a region of the textile to which the pretreatment liquid is applied. ### Claim 17 (depends on 5) A recording method comprising: applying the pretreatment liquid according to claim 5 to a textile; and applying by an ink jet method an ink composition containing a pigment to a region of the textile to which the pretreatment liquid is applied. ### Claim 18 (depends on 6) A recording method comprising: applying the pretreatment liquid according to claim 6 to a textile; and applying by an ink jet method an ink composition containing a pigment to a region of the textile to which the pretreatment liquid is applied. ### Claim 19 (depends on 13) The recording method according to claim 13, wherein the pretreatment liquid is applied by an ink jet method.
